P0300 Code common, but no other codes
I will first state that I did a search on Check Engine Light and they all addressed other codes and usually were associated with a mod of some kind.
Several times in the last two weeks I have started my car and had a misfire. Always upon start-up. It would run rough for a few minutes, then clear up. Yesterday Check Engine Light came on and is still on. I checked for error codes and got P0300 and U1064 in the A0-LDCM and A1-RCDM sections. U1064 (Loss of communication with DCM) doesn't seem to mean anything according to the list of codes I have. I have reset these codes and the Check Engine Light is still on. Any way for Me to shut it off?
Could the problem be either junk in the fuel or maybe water? I have been buying my gas at the same 76 stations since it was built. We have had unusally bad weather in Las Vegas and it could be condensation from the gas station tank.
Any ideas?
Thanks,
