Occasionally, my car will die in certain situations. Sometimes when I shift into nuetral to reduce speed when approaching an intersection or toll. The car will just die and all the dash lights come on. Also sometimes when I'm stopped at a light, the idle will drop down and come back up again and die some of the time.

I thought it might have been the battery since it seemed to happen when blasting the heat, but I just had it replaced two days ago, and it still happens. I also recently replaced the ignition module, ignition coil, spark plug wires, dist cap/rotor (all MSD), so I thought it might be the alternator. The car drives smooth and performs great, it just cuts out on me occasionally, never stalled on me while in gear/in motion, only seems to be when I'm stopped or in neutral. I also tested the alternator and thats fine too.

And very seldomly, when I start the car and its freezing outside, the idle bounces up and down for a few seconds, but this doesn't happen often.

Any thoughts? I just ordered an ignition coil to have that replaced but I don't think thats the problem.

sounds like you need to adjust your idle screw or at least did you try that first before you changed everything?

 

No I have not tried adjusting the idle screw, I actually replaced everything else to solve a few other issues I was having (which worked), I also felt like replacing the battery since it has been quite some time anyways. The only issue I was left with was the car dying.

Adjusting the idle screw doesn't seem like a bad idea. Is this something I should try to do myself? I think I've heard others ward against it. The idea would be to increase the idle?

Thanks for your reply BTW.

try cleaning out the iacv. it can get quite clogged up and cause idle issues

 

I actually had that done since a lot of people mention that... (Cleaning out the IACV)

i had the same prob on my h23, i just bought a new iacv...i think cleaning my old one would have done the same thing.
