Thread: Car sputtering after shut off, after installing Intercooler

Not kidding its like it is dieseling. It happens maybe every 2-3 times I turn it off it just kinda sputters and wants to stay running.

What gaskets did you use etc?

The gm gaskets for the GenV both gaskets. lim to core and blower to core vacuum is good around 20-21

pvc clear? Pull the oil cap off and see if it does it when shutting it off.

PCV is clear and did the something with the oil cap off.

Car idle didn't sound to bad from what I could here. Did you check your IAC and MAF? Make sure you didn't get any coolant in the motor oil

Dee, how would this effect the engine when he turns it off?

SUB'D

guys this thread is 3 months old i'm sure he figured it out by now.

That's it...I'm going to follow what I thought of earlier...

Hi Dan!

HI bill

Oh god why is this alive. I never drilled the pcv hole on the IC core. Putting a breather in place of oil cap solved the issue.

I was just throwing random things at him for him to check. Its obvious that he running to rich, check fuel psi and make sure the fuel regulator and injectors are working properly(voltage, etc)

You suggested coolant in the oil ..... ???????? Still makes no sense as to how that could have solved the problem he was having. Acid..thanks for mentioning what it was that fixed it.

What, are u trying to make a point or something? Well its pointless if u are.....I didnt know what his main cause was so i was just trying to help. Dont come at me when I may say something that has nothing to do with the cars issue, but how bout u give a thumbs up when somebody does give accurate and correct info....

Dee, I'm not coming at you, I'm trying to understand what your suggestion is getting at. Your suggestion of checking the oil for coolant didn't make sense to me as to how that would cause the car to keep sputtering after it was shut off. I asked you to clarify, because on a daily basis I learn new stuff. I learn because I'm willing to say to myself "I don't know everything". In taking this attitude I've learned a lot that didn't appear to make any sense to me at all, so I asked you how that tied into the sputtering. My diagnostic approach is to suggest things that are relevant to the issue at hand to get the car fixed quickly.
