Car is running great made 440hp at the tire. Went to Big 3 Racing.However one problem, the car doesn't want to hold an idle well, especially when motor is warm and been running a while. The tuner said that my hose going into the iac valve is pinching and cuting air causing the rough idle. That I need to order some hardware from vortech, new hoses, intake piping etc, that some air getting in could mess with the maf sensor. He said the iac valve is ok. Im sure that isn't it, hoses look fine to me.After the car is warm and running for a while and I turn it off, when I try to turn it back on it starts up fine, but won't hold idle and stalls out. Any thoughts on what could be going on? Thanks</blockquote>
