...that it does it in the mornings after the car has sat all night. On the way to work when coming to a stop or slowing to take a curve. Heres the strange part. After I get off work, the car does'nt do it at all on the way home. Could'nt find a vacuum leak. Cleaned the IAC, checked under the hood at night to see if any arcing going on. NADA. If it was a vacuum leak it would do it all the time which might be the same if it were a faulty electrical connection too. It never did it in the hotter months that I can recall. So...any ideas. Maybe a bad ignition coil or module going out. But why the change between the morning time and getting off work? Today through a drive thru window (for food) the car idled dead on 1000 rpms and did'nt rev up or down. The car bumped a few times and thats it. There is no codes nor is the ECM throwing any. I even unhooked the battery cable to reset the ECM. NO GO. Gettin' kinda irritating now. Help!!!!!

mine does that when i put 91 octane in the tank dont know why but it does.

 

Sounds like my car when its completely cold, I have to let the thing sit for 5-10 min before it'll run normal. When I bump the gas it's delayed, so it revs up after Ive already let off (just a bump not like Im flooring it) Never have to deal with that issue unless its been sitting for 8+ hrs, but overnight it could sit for 6 and still do that.

As far as my car goes, Im starting to wonder if it has to do with the throttle/butterfly valve. Then Ive been reading that some people's have been stuck fully open recently, I wonder if the valve is getting sticky, esp with the cold weather. My guess is if its the same problem Im having that it's doing the opposite, getting stuck almost closed or just enough for the car to die. My idle is 1000 warm, not sure why (well part is my coolant temp sensor, bad wire so it constantly reads super low, just no motivation to find it) but right now as long as it stays running and doesnt blow up Im not entirely too worried.

Try cleaning the intake, cant hurt even if it isnt that.

 

i had a problem liek that with the rs only diff is it did it wether the car was warm or not, or if it wa ssitting or not, check all the wires in the distributor, once in a while one of those wires wil crack inside the insulation and will reak havoc with stalling, and car not starting all the time
