R32 GTS Turning Off When Warm Help!!

[Juvv]

hey guys,

My car has been stuffing up as of late. When its cold it seems to crank over easily, but as soon as it warms up, on idle it just stalls and turns off and i cant crank it back over.

Im guessing its the earthing problem that i have been reading about but i just wanted to make sure.

Today i also put in a set of splitfire coil packs with the same result.

Thanks guys,

Jacob

Hey man, I'm having the same problem with my r32 but when i did a ecu check it told me(after i let the engine warm up) that something was wrong with the knock sensor. I'm not really sure what the knock sensor does but i'm gonna have a look see and post my result. Let me know if you come up with anything.

yeah cool post up in here man, so i can read what you did to fix it lol.

i havent done an ecu check yet, seems to complicated lol

Hey Juvv my car starts normally again. After checking all the electrical stuff like running an ecu check and other stuff it turned up nothing. So i decided to lift the head of the car and guess what? We found leaking valves man. So this is what you do run a compression test on each cylinder. The compression on each should be between 110- 140psi. Let me know whats up. If the compression is below 100psi,get your mechanic and you buy some new valves or grind the ones you have is they didn't melt or aren't burnt badly.

ahh wow.

ive jsut replaced the coil packs, and sparkplugs with no change

so this might be worth having a go of! how much were the valves? or didnt u have to fix anythign

when it gets really hot next and won't start, check if it has spark (timing light), if its got no spark, then its your CAS.

You might want to check your ignition relays and other relays as well... just a suggestion, swap them with another car or something to test.

Well after pulling out my valves we saw that they weren't seated properly so we grinded the ones that i already had. And now i'm starting one click even when its hot. Exactlly what is the "CAS?" Check the compression on the engine and lets see what its saying. Remember if its less than 100psi your valves are the problem. The compression is leaking pass the valves due to the head warping.

CAS is crank angle sensor
