my recently acquired 240 is doing some weird shit.


Ive been converting it to a drift car, took out the seats etc.

I went to crank it up the other day, dead... just tick tick tick.

new battery and now it runs rough, like its missing an engine mount (it isnt)

slowly slowly decreasing in rpms til it finally dies (over a 5 minute period or so.)

I had a vacuum leak in the cold air intake, fixed it, but still the same. when I get it up in rpms it runs so so. it bogs on occasion, til finally it doesnt want to go anymore.

the cars new to me, everything looks okay, anything I can try? alternator maybe?

bookoo

Check timing...had a ka do that to me the dizzy was turned all the way to retarded and wouldn't do anything but bog..check for more vac leaks...but the alt, start the car, then unhook the battery and see if it dies if so then of corse alt is bad. Otherwise look for more vac leaks...get some brake cleaner and spray it down and see what happens.

Also is the idle roaming..?


Iac valve if so.

Evolutionz

unhook which part of battery? positive?

idle doesnt really roam, it just slowly decreases in short jumpy increments.

Evolutionz

unhooked negative... car didnt change at all.

driftxninja

does your motor shake violently like its possessed by satan himself?

Evolutionz

Yes! Extremely bad

Evolutionz

update, just got home, car cranks sounds like its misfiring and wont turnover. exhaust makes potato gun noises. no bueno.

ive checked nearly all lines, nothing is different.

Spark plug wires in the right order? spark plugs and or wires may not be working properly. And if you hear a tick noise from your starter your starter is bad. Every starter has its solenoid and when it loses the ability to get power it makes that noise.

Evolutionz

the motor is turning, starter is good. should I just check plugs? like wtfff

Evolutionz

I hear a whining noise when the key is on, doesnt go away. mean anything? it sounds like it wants to start, but no bueno.

also, extremely low oil... that cause it?

Evolutionz

now the car for sure wont start, it rocks really really hard and wont get up past a 100 or so rpms. every so often it gets close to 500 and tries to officially start, then bogs down. there is still potato gun noises from the exhaust.

someone help!

driftxninja

could be fuel injectors.

check that all your injectors are firing. make sure that your fuel pump is priming and working correctly. make sure you are getting spark and that your wires are dry.

ive had a similar problem with a previous 240 where i would be driving and one cylinder would randomly stop firing and the motor shakes horribly. it was the fuel injector stopped firing so the cylinder wasn't going.

so also make sure your spark plugs are in the correct order.

driftxninja

you could have jumped timing also which is why it won't start now

ericcastro

first thing, make sure to get some oil in it right away !!

After that, do your spark plugs, car, and rotor.

Then go to auto zone and borrow the timing gun and buy some starter fluid.

try to get the engine started so you can check the timing.
(if not, no worries)

try and have someone turn the engine over for you and spray the starter fluid around different areas on the hoses, intake. If the idle picks up, you have a crack in the hose or intake.

also wouldnt hurt to take the fuel line out on the engine side, put it in a empty water bottle and try and turn the car over. is fuel going into the bottle?


where does this whine noise come from.

okay, on occasion of me manually trying to crank it, using the starter, it will sit pretty at 400 rpms for a few seconds once I stop, then fallonface...

just changed oil to full synthetic sexy ass pennzoil. spark plugs are on the counter, ran out of daylight. there is a tad bit oil in cylinder 3 from when I just redid the guide gaskets for the valve cover, the previous one was cracked and leaking... I dont think thats it. Im hoping it may be an injector, im scared its timing related.

I just read this http://zilvia.net/f/tech-talk/384511...ls-like-2.html

and it seems like thats it. from what people have said, I think mine will be fuel related. the battery died super hard recently, and this is all derived from that, new battery, now running rough and now even worse, sounds like injector took a shit. are these expensive? should I upgrade? direct OEM? just curious.

When its light out Ill have more answers.

Evolutionz

just got to work on it, pulled valve cover to look for weird shit, looks fine I suppose.

went to change the plugs, the second one from the front is stuck, I mean, Im a strong guy, and it clicks and wont budge, tried several different wrenches. da fuck... leave it and move on or what?

!Zar!

Maybe you need to reinstall your interior.

changed the three plugs I could, now its starts and runs, but not good, still kinda like its been possessed by satan. and when I give it gas it gets all retard.

Im thinking this is fuel, or hoping so, having hard time getting the rail off, I have to run to work and will be back at 6 to finish getting injectors out to see if one is faulty.

if not what else could this be?

ericcastro

Get some pb blaster or some liquid wrench and keep drenching that plug. dont crank on it to hard, or it will break in the head or strip out the threads.

Soak it for an hour, give it a couple tries to jar it loose, not long pushes. If it doesnt give, keep soaking it.

You could tap the socket with a hammer a few times to in an attempt to jar/vibrate the plug out of those threads.

Ive got wetness all around my fuel rail... Ill be taking it off in the morning to investigate further. but its got spray all over the inside of my engine bay, Im just now noticing it I think

Evolutionz

also! it runs rough, getting lower in rpms til its at retard shaky idle. likes its missing or something, someone post up a firing order please, mine is just 1,2,3,4 all the way around on the distributor cap. maybe I went retard and messed stuff up.

if I keep it at 2K with my foot it wont fluctuate, it sits pretty. but idles like shit. and there is a whining noise when my keys on but not turning from Id like to say passenger side, in the engine bay towards the bottom, weird.

driftxninja

firing order is 1, 2 , 4, 3 bro

driftxninja

going clockwise.

Evolutionz

firing order is right, My car now starts up and runs fine for a few seconds. then it bogs out, its not from the start anymore. MAF? something like that? orrr what

so sincerely, go fuck yourself.

This is my daily, if you cant help, shove off.

Im getting a buddy that has literally 20 240s to come help me figure it out, he thinks its an injector or the Maf. we'll see

!Zar!

20 240's?

Why the fuck...


Oh wait, I just noticed.

check the maf....

pandaroo

you said when you turn it over it makes potato gun noises which leads me to believe that your timing chain had a big jump and the valves opening at completely the wrong time.
