Damn, you're the man. Thanks for the quick reply! Well I can't argue with you, you clearly know your stuff. After researching your analysis, it seems like a pretty spot on place to start. Was hoping it would be something a little easier though! I've done all suspension and bunch of other stuff, but I'm kind of limited in confidence and work space (apartment) when it comes to taking engine pieces off and such.
I think i'll start with cleaning the MAF, probably won't help, but it's never been done, and is easy...so no harm no foul WHEN it doesn't work.
To do a mobile mechanic looks to be about $450 for IACV replacement. Last question, can this lead to other problems if not taken care of quickly? As it's not too much of a nuisance at this time.
