codes p0740 and p0301


Recommended Posts

I have a 2000 996 convertable tiptronic with 78k on it. Its been running really good since I changed the MAF about 3 months ago and put new breaks on it. I live in LA and its been raining for 5 days straight and the car has been outside. I went to drive it the other day and it sounded a little rough and I backed out of driveway and started to take off and it was really rough with no power and I looked down and the check engine light was flashing so I shut it down and I have a reader that was in the car and it gave me those two codes (Po740 and P0301). I checked the ATF and that is low so I believe that will take care of the p0740 but I am concerned about the p0301 cylinder 1 misfire. is this computer controlled and something got wet? A spark plug wire, a coil? If I start the engine can it to further damage? Could it be a bad cylender?

Thanks

please let me know if you need more info?
