heres what happening with my car, when I first start it up it doesn't want to idle and will occasionally die, but once it is warmed up it runs fine and the CEL light is on, but only when the motor is running, it wont stay on without the car running so I can't do the thing with the key to see how many times it flashes. Here is what I've done, I thought it was the egr valve so I got a new one and that didnt' fix the problem, reset the ecu still get the light and it still doesnt' want to run cold. I've went over all the vacuum lines and I can't see or hear any leaks, i've cleaned out the throttle body, checked the plugs and wires. The car is a 96 GS with a cold air intake as the only thing done to the motor and I'm at 78k miles. Does anyone have any clue what the deal is, I don't have a scan tool so I can't pull the code that way, i went to autozone since they do it for free ane they told me they can't do foreign cars, which I argued that is is a mopar engine and the same as an american eagle talon and they said they might get in trouble if they did it. I am completely clueless on what to even think about what could be wrong with it. my theory is it has to be in the emissions or the vaccum since it only does it when its cold. thanks for any help.
