After doing heads cam and intake, i got her tuned and then i started to stall at idle...be ok untill it was warm then kinda died then kicked up, but finally would die. So at 1st i thought with the stage 1 cams the idle just needed to be bumped. so we did that and it was better for a little, but at times still bad. it started to and now when driving at constant speeds it bumps while cruzing and then at idle it will go to stall and save it self and at times stall totally. this happens at random, some times its ok( idle still is a little rought at times, theoil pressure will flicker ata lot, but wont stall some times) I thought it was the EGR and i took it apart and seemed to be working, put a vac up to it ect. i cleaned it out as well at the tb side. still happend.

could the egr just be bad and replace it, or could this possible be a TPS problem? i have to find my volt meter to check the TPS, but b4 i do that does that sound like that could be the problem?

edit: also i havnt thrown anycodes at all...

that could be a number of things, like the motor not getting enough air flow thru the iac, you need to go to a good tuner that can read the st fuel trim and see where it is.

IAC has zero to do with anything above idle.

The fact the issue seems to be progressive I'd go with something getting clogged or cam sensor is giving up the ghost.

Add fuel. Thats all a tuner does to tune for a cam is add fuel till it idles right. Can you believe people actualy pay for custom tunes for $400-$500 when you can just buy a wideband for $300 and do what they do. But to tune for a cam you don't need a wideband just go richer.

would that make it only sometimes though? is it worth checking the tps? or does that not sound like a problem that would cause

IF iac has zero to do with anything above idle then explain the IAC MODin the how to section??
