Ok, so intermittent no start issue. Trying to brainstorm before I start throwing parts together. About a 50/50 chance that my car starts as it should, shoot up to 1500 and then drop back down to around 750. This is normal. Recently however, it will shoot up to about 500, and either run rough or die completely. If I can get it going on the road for a couple min, everything smoothes out. Any thoughts? My first one was IAC, but I replaced it with no affect. What would be the best way to test the iac wiring? That's my next guess.
