Hey guys I just got back home from running the tail of the dragon last weekend and my check engine light has come on. Its a code P0300 Random Misfire. I spent the next 2 day s trying to find what is causing it. All my spark plugs and spark plug wires are new as of this year. I do not have a vacuum leak anywhere witch makes me believe its still electrical. I took off my throttle bodies and cleaned them and noticed the driver side intake manifold its full of OIL! I cleaned it all out and reset the ECU. So far it is running very well with no more misfires.
Has anyone else had this problem? Do I need to instal a catch can to prevent this problem form happening again? My car is a 01 ACR
