Aloha All,
My engine check light comes occasionally ON and I get a P0300 & P0171. In addition, my car valves appear to be pinging especially when I am accelerating when driving on an incline. I've tried to clean the MAS using a MAS cleaner and already replaced the spark plugs. The engine light stayed OFF for only two days. I appear to have a vacuum leak somewhere near the intake manifold. I sprayed curbarator cleaner around the intake manifold and fuel injectors and have not determine where it is coming from. Any help is appreciated.
