The tps reads 0 as well as the iac that's what's tripping me out

You have a Vac leak or TB is open too much..
that or it's really lean

Check to make sure your IAC is wired properly. The Holly Sniper TB I worked with came with took a 2000 to 2003 Dodge 2500/3500 V10 IAC. Plugs up the same but wires differently
Thanks ill tell him to try the plug because we already closed the tb all the way and the fuel trims and mv aren't that far off at idle.

I actually ended up changing the TB to a Top Street Performance 92mm TB. Uses the GM IAC and TPS. I personally couldn't get it to idle down til I did that. But then again I'm not the brightest bulb on the tree. Lol
Have you had any luck with this?
I havent had the chance to get to him. Been busy with school. Ill try and get to it Sunday. He was going to take apart the intake manifold again and try to look for vacuum leaks.
