car stalls in the middle of driving - Toyota Yaris Forums

The symptoms that you describe most likely would be a clogged iac valve. IE Idle air control valve. Due to carbon buildup. Remove the air box tubing assembly and spray carb cleaner liberally while someone presses the throttle inside the car. Key on engine off and whipe with a rag all the black soot. Try to look for any ports and spray carb cleaner in those as well.

If the maf was defective you would have a consistant check engine light code. Most likely for low air volume. Which could be caused also by a completely clogged air filter that has never been changed.

Try cleaning iac first its the most likely culprit on a vehicle that is newer but has a lot of miles in a short period of time.
