Hi all,
I have been driving my car every day for the last 7 days, the Catalyst and Oxygen Sensor Heater are still showing incomplete, today I drove about 20 miles out stopped for a while and then drove back and they are still not cleared but I now also have a P0300 engine misfire, I had not had the misfire until today. I do not have a secondary air system anymore so I removed that one. Is there anyway to get the others cleared or do I just keep driving. If I try to clear the P0300 then I will be starting back at the beginning. Please send me your thoughts and suggestions. I am attaching my latest tune and it seems to be close.
Thank you for your time
Mark
