Had heads replaced. Stalling while in idle and at lighted intersections place in park starts right up. (No check engine light at all)

Replaced, crank sensor, cam sensor, throttle body (and its connection on wiring harness) MAF sensor, MAP sensor, oil pressure sensor, and coolant temperature sensor...

Still stalling! No check engine light, still running on oil shop put in after repairs. Not synthetic (What I've always used in car since I've had it)

Suggestions much appreciated!!
