Car sputters and has no power!

[SidewayZ-SR]

Hey guys, I somewhat have an idea of what i think might be causing the problem. Would like your professional input of what you may think it is. So i got my 95 240 up and running today, and i just recently dropped a 95 sr into it. So i got it up and running finally today and drove it around and whenever i give it gas, the car sputters and doesnt wanna go. Feels like it has no power what so ever, so i'm thinking it could either be an injector leak, or my timing is off. When the car is idle it goes down to about 400RPM then jumps back up fast to around 700rpm's, then back down so on and so forth. Thanks guys! Really appreciate it.:bowdown:

[DALAZ_68]

lol sounds like my car and i have a KA lol


might be air leak, timing

might wanna check ur tuning...

[SidewayZ-SR]

Anyone else know something that can be causing this? Thanks.

[xxxjovaxxx]

have u checked ur mafs?

[SidewayZ-SR]

I checked them when i plugged them in, could they be bad/not pluged in you mean?

[sTalnOut]

i would check the MAF , TPS,get carb.cleaner to clean the trottle body,and check all pipes n hoses to see if there is any leak.

[SidewayZ-SR]

Alright I'll check out the MAF. What else should i be looking for on the MAF besides it being unpluged? Thanks a lot guys.

[SidewayZ-SR]

Sorry to sound noob guys, but im new to turbo cars, and yes this is my 1st. So i really dont' know what this part is called, but it hooks up to the intake/actuator/IC piping. And it looks like a piece of the wire harness is supposed to connect to it, but on mine, there is nothing connected! Any more help guys? I greatly appreciate it.

maf shouldn't affect idle... your idle issue sounds like a vacuum leak... as far as the stumbling... that could be your MAF issue... may also be a boost leak.

[SidewayZ-SR]

Alright, i gotcha. Thanks for the advice i'll have to check tomorrow in the day time. But as far as the pic that i posted, is there wires supposed to be connected to that piece?

[nicku]

my car had the exactly same problem before...and we didnt think it could be the timing...because the timing has to be way off in order to make the car act like that...but it turned out to be the timing was wayyyyyyyyy off...

You're making me feel A LOT safer! I'm honestly hoping it is my timing, i just need to find a timing gun, and check my timing! Also, was it an SR engine? or was it the KA? Really appreciate all of your inputs! Does anyone know what the picture i posted is?

[S13Leprechaun]

^^^ not sure about the pic cause i dont have an sr, but are you SURE all the spark plug wires and plugs are in correctly and all the way? cause this happened to me before too and thats what it was.. but it was a KA tho... other than that i think its ur timing as well... gl.

[SidewayZ-SR]

Yeah pretty sure all the spark plugs are in, and everything is down all the way. I honestly hope i didnt buy a bunk engine!

[S13Leprechaun]

naw man... u didnt.. its something little you gotta fix... u must have either a leak or ur timing is fucked.. check those two things... also, reset ur ecu... just unplug your battery for 5 mins.. it does the trick sometimes when u do new stuff.

[SidewayZ-SR]

Gotcha, well i have a whole new FMIC setup, should i slap that on? And wouldn't that eliminate any leaks that i would have had? :) It probably is my timing, i'm honestly hoping it is, but you've been a great help :)

[S13Leprechaun]

that wont eliminate a vaccuum leak thats somewhere in the intake manifold or something no... but i seriously doubt its anything that has to do with your intercooler system,and i dont think it would be a boost leak... unless it only does it while you are in boost.. does it do it even before boost? if you dont know, go run it and see when it starts runnin like shit... and judging by ur idle description its either a leak or timing like i said... check those.. im not sure if the timing is the same as a KA but the KA timing is supposed to be set at +15 i believe... it goes left to right in incriments you know what i mean? so search and find out the timing and go set it to that. if that doesnt change anything, search for leaks.

[SidewayZ-SR]

It starts to do it around 3,000RPMS before boost kicks in. I can feel it wanna boost and let out power, but it just sputters and doesn't let any power out! I honestly pray to god its only my timing!

[S13Leprechaun]

well if its a stock sr, it should wanting to or starting to hit boost at or before 3,000rpm's if im not mistaken... so you may have a boost leak... does it continue to accelerate above 3 g's or is it like a rev limiter at 3 g's and wont rev any higher?

[Mathetai]

:-/ :ugh: :confused: :loco: :tweak: :keke: :ghey: Haha. just wait and I will get a timing gun from Justin and we can check it this weekend.

your maf sounds like it's either bad or wired in incorrectly... the maf starts to affect things at about 2700 RPMs if I am remembering right... Also, does the problem exist while you are sitting still and revving the motor or only while under load? If it does it only under load you're looking at a boost leak.

[Mathetai]

I can answer for him since I did the swap (but not the wiring). It seems to idle ok but occasionally it sounds like it missfires. Like a little hiccup. Revving sounds great and linear but no power when driving.

[DOOK]

putting the front mount kit may eliminate a boost leak if you're putting on all new couplers and piping... are the ends of your hot and cold pipes rolled? Hopefully so, if not, work with what you can or get new. change all the couplers that look suspect and double check the MAF. Like I said, the wiring could be good, MAFs do go bad occasionally.

[Landers]

this sounds a lot like what happened to my SR when i dropped it in...if it idles and sounds like its cammed and you dont get any power after like 3000 rpms i would check out your ignitor chip....turns out one of my wires was disconnected and i was only runing on 3 cylinders....made the power feel like a Ka. just a thought...eventhough it sounds like a timing issue its just another thing to check out! (FYI i only skimmed through your thread because im trying to do this fast before my boss catches me on zilvia!)

[SidewayZ-SR]

Hey Poop Mouth, aka Mathetai, Where are you? How are you online and at work?!

[hrdprkin180]

does it sputter when u drive it normal or when u romp on it? If its both then I want to say its timing. My last Sr did the same thing but only when I stomped on it, so did my buddy Jeramys car. Carb cleaner the Maf, throttle body, and you might want to check ur injectors. for me it was the injectors.... But dude if ur cars loud as shit and sounds like ass, then i would with a good check of ur exhaust system.

[Mathetai]

Hey Poop Mouth, aka Mathetai, Where are you? How are you online and at work?!

Muahahahaha :naughty:

[SidewayZ-SR]

It does it when i floor it. Gets up to about 3,000rpms, and then after that BARELY goes up any, cuz all it does is sputter. Just installed my exhaust lastnight, thats fine. What was wrong with your buddy Jeramys car?

[SidewayZ-SR]

So i check my coil packs today and they all seemed to be pluged in fine. But when i disconnected the coil packs from the wire harness, i noticed a piece was missing. Would this have anything to do with my car acting gay?

[posdriftin]

if you ease into it does it run ok if so clean the throttle body and maf... mine was the car hardpark was talking about... runs great now... also try changing the plugs..

[SidewayZ-SR]

Yeah, it runs fine if i just ease into it. I'll try cleaning the throttle body and the maf. They are brand new spark plugs! They came already gaped, but do they have to be gaped to a specific amount? Thanks!

[rlpinoy]

jus to ask: are you running an upgraded fuel pump or the stock one from the ka? i had this problem until i upgraded to the walbro 255.

[SidewayZ-SR]

Using the stock one from the KA. Didnt mess with anything with the fuel pump! You think i might be needing an upgraded fuel pump?

[rlpinoy]

mine sputtered like that too but once i changed it now it pulls like a mother. the ka fuel pump is too weak for the motor. your depriving your car of gas. correct me if im wrong plz. ask far as i know you need to upgrade.

[SidewayZ-SR]

Alright cool. I'll check that out after i check and see how off my timing is! But thanks for the info dude, i hope i get this solved. It honestly bugs the crap out of me when i drive it, so i dont' even drive it!

[rlpinoy]

does your car knock or shake a lot? if so then it prolly is your timing. if not then upgrade to a walbro 255. its does wonders! lmk if that works. if not then most likely leaking somewhere big. check leaks before buying the pump and save your money.

[SidewayZ-SR]

I've checked for leaks i can't find any! :( Could i use the stock fuel pump that is on the s14 sr clip i purchased? Or is that basically the same thing i have. Yeah my car shakes and it idles really funny. Do you know what this is? and if i really need it. Its part of the IC piping, but gets connected to the fuse box which i don't have on my ka fuse box.

[posdriftin]

i have never seen a fuel pump come on a clip ... a fuel filter yes ... get z32 fuel filter

[SidewayZ-SR]

Alright gotcha. I really hope i get my car up and running!

[rlpinoy]

from the sound of it everything is cool just buy a new fuel filter might be clogged like hell. does your car sputter when you first start going? if so then you need to change your fuel pump. the one that came with yours might be bad. Mine was doing that until i changed the pump. wasnt pushing enough fuel into the motor.

[czarli]

I have the same problem on my KA, I ordered TPS sensor once I install it I will let you know if it helped

[czarli]

Could it also be a knock sensor? I had a VR4 and after going from piggy back to stock with out knock sensor it wouldn't misfire but it wouldn't accelarate evenly... Still waitning for TPS sensor

[kingkilburn]

Maybe he should ask Mr. Meph. lol

I think you need that. That's the boost pressure sensor.

[JDMwannaBE]

when your sitting still can you rev it past 2500 rpm's? if not it sounds like a MAF problem.

[rlpinoy]

u fix the problem yet?

[SidewayZ-s14]

Fixed. Was my fuel pump. Thanks guys.

[rlpinoy]

see thought it was when i first read the symptoms. good luck bro with the new found money pit!

[SidewayZ-s14]

Lmao money pit. You're telling me. My coolant line is already leaking :( So many problems with turbo engines.

[rlpinoy]

so many problems but so much fun fixing them all. recently ive changed:
alternator, power steering pump, battery, turbo, manifold ,wastegate, elbow, ecu, ignitor chip, gauge cluster, fuel pump,blah blah blah all without knowing what to do other than asking for help and searching forums. thx for zilvia and friends with sr's already.

[SidewayZ-s14]

Did you change those because you wanted to upgrade, or were they just bad on the engine you bought? Hopefully mine isnt that bad.

[rlpinoy]

gauge cluster had to switch from sohc to dohc. fuel pump, turbo, ignitor chip, power steering, and turbo elbow and manifold were all bad. Battery had to change cuz of fmic and alternator changed cuz my sohc was warrentied for life by autozone.

[SR_Elliott24]

I had this problem when i first put in my SR turned out to be the MAF.
