Engine stall when I move transmission to D or R, also on low speed. What it might be?

Question

2007 Suzuki Grand Vitara 2.7 AT, engine stall when I move transmission handle to D or R, also on very low speed. What it might be? No code at all

Answer 1

You will not set a code when the RPM is low. The Idle air control maintains a target RPM. The fix you can do throttle body cleaning . When that is done check the idle speed with the a/c in the on position.
