yeah it was the idle speed control valve!! I had one lying around the entire time and ended up spending around 346 and some change for nothing.... well not entirely but I changed the fuel pump, filter and ecu. oh well at least I know that shiet is newer

Another problem I ran into was that with an aftermarket filter kit, the cooling fan can blow into the intake area around and into the filter causing an erratic idle. I moved it further forward and out of the fans airflow and it cured my problem. The ISC can be a problem too, but the filter should have a shield around it if it is just stuck on the end or the AFM like mine is.

Good luck and let us know how it goes.
