hey guys, can ya help me out a bit? my car is stumbling at idle. when you start it cold, the engine runs fine, but as soon as it warms up, it runs like ass!, lopes etc,, but NOT consistently though, so today i got the balls to drive it on the freeway like 12 miles. it runs great on the road, but when you come to a stop it wants to stall out, the CEL came on on the freeway, but after i shut it off and started back up the CEL went out, but still runs shitty. i was thinking a bad throttle body? or iacv?, or maybe a tps? i know you can run a car just fine with a bad o2, so i dont think that is the issue,,, can you all maybe give me advice?
