.. the idle drops quickly that it stalls. The only cure is to quickly step on the gas and let it rev for a minute and then she'll hold the idle at 550rpm and it's fine to drive around without stalling or loss of power. What could it be??[/align]__________________

microswitch in tps is not being made (to signal computer to start idleair motor)or idle air motor is not working

 

fixed the problem..I cleaned the IACV with throttle body cleaner and I also sprayed the throttle plate. Now she starts like a champ!!!

 

I love when that happens, success!
