I've been having this problem for the past 6+ months...

When I drive my car for like 15-20 min and I turn it off and try to start it up like 5 min later it always wants to stall on me.

I've replaced my battery, plugs and wires. I've also tried 3 different tunes, also tried raising the idle rpm's and still nothing.

2007 auto 30k miles.
Motive 3.73 gears
Livewires
Shorty Headers
S&B Intake
Tune

Does anyone have an ideas? I'm not sure what it could be at this point. It only seems to happen if it's 70+ degrees outside and the car must be warm.

Thanks

 

Ohh also for what it's worth...

When I start up my car and hurry up and put it into reverse the car wont even think about stalling. Same thing if I start the car up and rev it up right away the car will be fine.

When driving it runs perfectly, other then getting bad gas miliage it hasn't ever given me any problems. I'm also running 93oct gas.

 

may need to adjust your idle, we had a similar problem on our boat.
edit: never mind, just read you already tried that

 

Yeah I even set it to 1k rpm's and it still would either stall or try to stall.

 

Well I got 2 new tunes from BamaChips (my old tunes were from vmp) and that seemed to have cured the problem.

Thanks Doug =)

 

07 with 30k miles? Make it "look" stock and drive it to the dealer and tell them fix your car and call you when it is fixed.
