hey guys, ive tried searching for similar problems but couldnt find similar listed symptoms. i was driving last night, not roughly, and after about 5-10 minutes the car just started to want to shut off. The tach would drop then catch again and finally when i came to a stop it really got bad. The car would idle really rough and when i would gas it the RPMs would drop. The gas pedal seemed to be doing the opposite of its normal operation. When i would give the car gas it would die. Eventually it died. Was able to crank it over a couple times and it would catch then die out. Soon after some friends pushed me up into some parking lot it started up fine then i parked it. From there i proceeded to try it again but after that it consistantly wouldnt idle for very long. Smelled like lotsa gas fumes. I have the stock maf on and a cold air intake that goes into the fender. other than that i just have exhaust (o/r with MILs) and suspension. Any suggestions?
 
Check the IAC. Remove it, clean it and see if that fixes it. Also make sure your don't have a vacuum hose loose. Any of the hoses connected to your air inlet to the throttle body or valve cover will cause it to shut down.
 
Hows the battery/alt? I had a problem with my charging system before I got my optima and my car did a similar thing to yours. Otherwise, maybe its a vacuum leak? check all your lines.
