While driving for awhile, my car starts with a slight vibration then it stutters and dies at a stop sign or red light. It starts right up again. I’ve taken it to the dealership had the fuel pump relay swapped with the fog lamp relay and main relay with th a/c relay, installed sensor assy-air flow. That was done in the month of Sept. Last week it stalled once, took it out today for a couple hours and it stalled twice. Any suggestions on what’s going on?? The car’s been great for 12 years. It has 106,400 miles. Thanks for any help.

Clean the throttle body and the IACV (idle air control valve) if it has one.
