Hey, I have an 02 LGT with 136k..the car bronked and bucked and it was thought the IACV needed to be replaced. I did that and now it is doing it again..Amy ideas?

Try your TPS.

Yeah, TPS, then MAF, O2 sensor; standard stuff.

a bad pcv might do it too.

The car was bucking and bronking, so I replaced all o2 sensors, and neutral positioning switch. The car was throwing a p1507 code and the bucking stopped. The car is a 5 speed MT, but sometimes the idle will drop so low that it will stall at say a light. I am going nuts over this issue. Thanks!

Stop randomly replacing things, all you're doing is wasting money.

Describe your problem in more detail so we can help you

Whoops, didn't read your whole post. Yes, that does sound like your iacv is acting up.
