KADE PROBLEMS!!! (Hepl please)

[hanz]

whats up zilvians.

ok ive posted and posted and searched and searched, but nothing.

PROBLEM: swapped a 95 KADE into my 89' s13. car idles nasty for about 15 seconds then dies. if i give it throttle dies even faster.

Background: i did everything you need to do for the swap.
car has a WALBRO 255.
car DID RUN FINE when on my friends s14

EMISSIONS REMOVED by some kid (supposedly did it correct)

THINGS IVE DONE:
Ive tried 3 different MAF's
2 diff. ECU's.
thought it might have a bad FPR, got 1 from the junky, same problem.
Ive dissconected each injector harness while idleing all injectors are doing their work.
NEW Z32 FILTER.


I HAVE A FEELING IT MIGHT BE THAT THE KID DID THE EMMISION REMOVAL WRONG, but when car idle i dont hear any air leaking, and YES he did block off the EGR.
BUT.. i believe he left the same lil intake manifold harness because it pluged right in the s13 engine harness. i dont know if that would make it a big problem where the car would die??

let me know what you guys thing please, ask me anything you want to know.


PLEASE SOMEONE HELP ME OUT, ITS BEEN DOING THIS SINCE THE SWAP LIKE 2 MONTHS AGO.

THANK YOU!!!!

Is the ECU spitting out and codes ??

[jorge1190]

check your vacuum lines mine did that exact same thing

[1slowS13]

idles nasty? like is it misfiring?

[hanz]

idles nasty? like is it misfiring?
feels like that when i give it throttle, like if it wants to choke its self.


check your vacuum lines mine did that exact same thing
ya i checked vacuum lines but since i dint do the emmisions revomal i dont know every single vacum line and lil sensor the kid fucked with. maybe theres a vacum line or something that i missed, but just dont know where.

i am going to do a vacumm pressure test.

im not sure how to do it but ill search online.

Is the ECU spitting out and codes ??

last time i checked NO the ecu was throwin out code 55 witch is NONE.
but i am going to check once more just to make sure.


PLEASE PEOPLE KEEP POSTING, ideas, similar experiences, thoughts, anything that would help me please..

THANKS AGAIN

the thing i will check is if the timming is correct??

[slothonaleash]

^^^+1 it sounds like your timing is off, reset it

or mess around with your idle air control valve adjuster screw

[Oo_Skyline_oO]

check your tps sensor, and listen arround your engine bay for a hissing noise, any hissing noise isn't normal and means vac leak

[tckracker]

Sounds like a bad Vacuum problem, most cars will act like that with a bad vac leak. Timing problems would usually have sputtering, bouncing idle, and strong smell of gasoline. Check your plugs and O2 sensor they can tell you alot too. You should have a steady vacuum when test it (Chiltons manual is a good source for diagnosing vacuum symptoms) GL

so right after the swap it didnt run right, is it running rich or lean? cause it almost sounds like its not getting enough fuel pressure is it possible that when the swap was done that a line got kinked.. or someone put the lines on the fuel rail the opposite way? just wondering

[hanz]

ok..

forgot to mention.

timing is perfect, my friend came and did it for me.
..
one of my friends said that maybe whats going on is that the fuel pump is priming ONLY so there is enough gas for the car to idle for 15 seconds but then the pump doesnt spit out fuel anymore and thats why the car dies..

But i dont think thats correct becoz, it still seems like theres pressure on the inlet fuel line at all times. and another thing if that was the problem, how come i cant rev the car not even passed 1500 RPM???? it just chokes itself when i step on it??

so yes, i will have to do a vacumm test to see if thats the issue.

ALSO.. i started the car WITHOUT the MAF being plugged in and it acted the exact same way??? like if its not even reading if the MAF is or IS NOT plugged in?? any ideas??

THANKS GUYS!

without the maf pluged in your car wont rev past 3k but if it dies before then most likely thats not the problem, if your worried ur maf is bad test it and the harness

[bloodie73]

My car acted almost the exact same way awhile back. It would start, then idle wilding for about 15sec then die. Found out it was running rich and one of my spark plug wires melted onto the plugs. Did you trying changing your plugs and wires yet?

[silviaz]

maybe a bad coolant sensor. The engine will run rich and the engine will die after a second. It's at the left of the valve cover.

[koukimonster139]

had the same exact problem with a friends car


bad ecu

[superaudi]

have u check the fuel pressure...?

YES, ive changed plugs, and wires, and distributor seems fine.

i got 1 from the junky and put it on last night, same crap...

had the same exact problem with a friends car


bad ecu

my ECU is fine, because i tried 2 already.


have u check the fuel pressure...?

NO, i have not checked fuel pressure yet, how can i check it?
but i changed the FPR and same problem so i dont think its FUEL PRESSURE.
But maybe yes it is running rich ass hell and choking on fuel??

thanks guys.
keep coming with ideas,and things to help out.

[silviaz]

You should take a look into the fuel pump, fuel pressure, and gas filter. The engine is not miss firing, you are telling it doesn't run rich..... you checked every vaccum......

I removed the emission, maybe I can help you. I'll snap some pictures about the vaccum you have to block.

[silviaz]

What to remove for the emission. My car is like that, KA24DE 1992. Engine runs very well and idle great.

Pay attention to the red, it's what I've done.

check it with a fuel pressure gauge....
so is it running rich or lean? :aw:
like while its running do u see black smoke or nothing coming from your tail pipe.....
just for shits and giggles try this .
1) buy a can of carb cleaner or brake clean
2) remove a vacuum line on your CAI plug the side going to your intake manny
3) have a buddy start the car while you spray either cleaner moderately into you CAI... if you can keep the car running of the cleaner you most likely have low fuel pressure

[projectRDM]

I'm pretty sure it's a vacuum leak, sounds just like a typical open line or kinked gasket. Have someone else start the car and literally soak the entire plenum with carb cleaner, if there's a leak it will pull it in and idle up for a sec.

Done.

[silviaz]

WTF, i'm trying to help and I got negative rep point.

[hanz]

OK ill try these things out, thanks guys, ill keep ya updated.

[loveskylines]

are the spark plug wires in the right order?

[Oo_Skyline_oO]

ok..

ALSO.. i started the car WITHOUT the MAF being plugged in and it acted the exact same way??? like if its not even reading if the MAF is or IS NOT plugged in?? any ideas??

THANKS GUYS!

uhhhhh HELLO!!!! no maf=runs like shit lol the maf/maf wiring is your problem, I can almost guarantee it. Also, check your brakes, if they sink in all the way and then don't come all the way and it feels like your brake booster is non existant, then that's your vacuum leak, so check the hose from your MBC and your intake manifold

[NismoS13Chuki]

sorry for the thread jack but i got my car with an egr delete and i get an egr code

duh! i know that, but i just disconected the maf to see if anything would change but nothing changed, how can i check if its the HARNESS??

This guy is ALWAYS right! :) He's helped me get through just about every problem i've had. :)

--I did a 97' obd II swap to my 95 and had quite a few "extra" vacuum lines left that i had to reroute and/or plug up. My swap didn't even start due to my drunken ass, ripping my entire distributor out and putting it into my new motor (which had None/removed by owner)...i never marked anything and i had to do the whole "top dead center" hooplah. yes yes i'm dumb :hammer:.

ANYWAYS.... Check vacuum and spark and GL :)

just wondering what you've tried so far, just keep us updated but really i dont think you maf is whats bad but if you wanna test your harness heres a way

if you have the FSM you can find out what terminals on the harness they're talking about

[Abstrak0ne]

If it sounds like a WRX, check your injectors.
