Car was taken to a dealer for routine service and the technician cleaned the throttle body, MAF, MAP and other sensors on the engine. I don’t know about the oxygen sensors. When I took the car in it was running well as it always had. When t got it back i didn’t notice any change in it until the next morning when the engine ran serging at engine speeds below 2000RPM. When the engine is warm the problem seems to disappear. I haven’t touched the engine but t bought some MAF and throttle body spray cleaner. I thought I’d ask if I was on the correct path and ask about the correct method for cleaning these parts.
