Fails to idle after warm start

Kooji · Mar 29th, 2006, 12:37 AM

Starting the car from cold is fine. The car starts, revs up then settles at around 1k-1.1k until it warms up a little then dips down to 750-800. However, as soon as it reaches normal operating temp, and I switch it off, then on again, it'll rev up, then dip down to 700, try to hold the idle, then fail and the engine just dies. It doesn't matter how often I try, it'll keep dieing. The only way to keep the engine on after the engine is warm is to give her a nudge of gas after the engine starts. If I leave it sitting for an hour or two, and try again, it'll start like it was cold (i.e. it starts without a problem).

A friend thinks it could be clogged injectors and that a normal tune-up will get rid of it.

Anyone know what this could mean? I suspect its probably something more 'important' than a tune-up.

Sounds like the MAF or TP sensor/connector problem I had. If you need more information on these, a search in this thread should return lots of discussions on the topics.

Thanks Animal. Will give it a shot today. From reading your previous posts, I've found out where the TP Sensor is...but no clue where the MAF sensor is. I don't a Hayes or Chilton manual to help me out.

I found this diagram, but it refers to a 96 Pathy. Still haven't checked if they're in the same location, but I thought it might come in handy for someone else.

It should look similar on yours, if I'm not mistaken. Every MAF I have seen has a similar appearance, though the location may vary. It can cause problems if it is dirty as well. Here's some instructions for cleaning it, though (gently) spraying it with carb cleaner seems to work well also.
