idles and often dies

[justin94]

Hey guys, got an issue. My '94 vic LX has 144,000 on it and often i am finding that when i sit at a stop light or a stop sign for a long time my car will idle way down and and sometimes-die. I then put it in neutral and it starts right up. It only does this once and a while but if i am in traffic it gets to be a pain in the ass. i just replaced a bunch of stuff on the fuel system. I put in a new fuel pump and its bracket, lines, and filter. what do you think is causing this? The battery? Alternator? Maf Sensor? or could it be a fuel issue?

The IAC can get carboned up and need to be cleaned. It could also be a vacuum leak, faulty EGR, dirty injectors, fuel filter (you did this) or the TPS.

Its time to replace your "Idle Speed Contol" valve. Its the one that controls the flow to the engine when at idle (or on a red light and stop sign). Its located behind the intake manifold on the drivers side. Its a hard one to reach and replace, you may have to take of the intake manifold just to replace this. I had the same problem with my 92 CV. I'm 100% sure of this, I've been in your shoes, traffic is horrible where I am too, and I had to put it in neutral every single stop or even a simple sudden step on the brakes. This can be a do it yourlef job, the part is only 50 dollars. Goodluck.

Hey thanks for getting me to look at al the aspects of this system. What i actually found to be the problem was that the cats were plugged with shit
