Car dies at idle

[CrucialOne]

Ok guys, this has got me puzzled. My 97 dies at idle, such as if im stopped at a redlight or such. It always starts right back up. The fuel pump has pressure and hold pressure to spec. The IAC has been replaced. Plugs & wires replaced not long ago. What else could it be? Something in the PCM? Has anyone else had this happen to them? Car has over 100k on it.

Anybody?

automatic transmission? Does it die every time you stop? What if you shift to neutral before you stop, does it still die?

Check the vac. lines. Esp. the one on the pass. side of the TB. Its known to pop off from time to time.

Yes, it is an auto. Doesnt die everytime. Shifting to neutral only helps if I keep giving it gas. Sometimes it spits and sputters and wants to die, but I'll give it more gas and it will even out. Things got me beat and po'd!

Re: Car dies at idle

ok, well that shoots my theory. I'll let ya know if I can think of anything else. But def. check your vacuum lines like ssms5411 said.

I'm just about ready to torch this thing!

How about the EGR? That will cause stalling at idle.... and many times on deceleration too. Giving it gas will keep it going. If there is no SES light though, it's going to be hard to test the EGR since it's probably electronic.

No engine light and no codes.

Re: Car dies at idle

Not setting a code doesn't necessarily mean there isn't a problem. A set code confirms a problem, but the absence of a code does not mean a problem is not there. It just means that the computer is not picking it up for some reason. You could try checking other posts on here that discuss the EGR blockoff plate. Disconnecting the EGR will of course turn on the light and set a code, but if it fixes your stalling problem, then you've found the culprit. Then you just get a new EGR valve. But you need to be sure because they are very expensive.

Or just say screw it and take it to the dealer for a diagnosis. Then you can decide if it's easy enough to fix yourself.

Go have it scanned; even if there's not a light, it may be throwing a code. Have you checked the MAF?

Re: Car dies at idle

I scanned it, but its not showing a code or any stored codes. Im thinking TPS or EGR, but not sure. Think I'll just hold off an screw with it this weekend.

Re: Car dies at idle

I'm getting an intermittent misfire right now that causes my car to shut off occasionally at idle. I think my issue is a coil. even though I usually don't get a code. You may want to get yours checked out along with your injectors.

Might be a good idea.
