I started my car today since there were no snow outside and the car has been in the garage for about 2 months. It started just fine but when the engine got hot the problem started. It doesnt respond well to the trottle and has a really rough idle sometimes it stalls. Then i waited for about 15 minutes and now it wont start at all. I had this problem before but i dont know why. Anybody got any ideas?

 

bad fuel, water in the fuel. might help if you said what car/engine it is. have you scanned for codes or tried to trouble shoot it at all? since it's a reoccuring problem i'd make sure i had a good tune up and scan it.

 

Well its a 1988 iroc-z and a 305 tpi. No codes so that is not the problem. I had this problem after i did a engine clening whit high pressure water. It runs great when its cold but when it gets hot it doesnt

 

I had these same problems - it was dirty and moist connectors at IAC and at 9 start injector - clean IAC and throttle check other connectors on all ignition system. Check ignition wire, get fuel to full and add some water remover additive....

 

Scania,

Check Ed's suggestions. It's possible that if you have an EFI engine the fuel pump turned over enough fuel after a bit of running that it mixed up any fuel/water/debris that may have separated in the tank.

I had a similar thing happen to me. It turned out to be moisture that had condensed in the distributor. The engine started normally, but as it warmed the moisture (ice) melted and vaporized, coating the inside of the distributor and killing the spark.

Start with the basics - fuel, air, ignition.

 

Thanks guys . Moisture is most likely the problem since its been in a cold garage for 2 months. Is it hard to remove the distributor cap? never done that before so a little help would bee nice

 

It's not hard to remove the cap exactly. Just a pain in the @$$ to get to.

 

Me too... you could have a crack small enough not to see...i would replace all my ignition parts..sounds like its needed a tuneup for quite some time...check to make sure your air dam is in tact also.
May as well have your ignition module tested while you have the cap off....
