Well my misfire seems to be getting worse. I installed a new DISA O-ring and cleaned the MAF. I also put some injector cleaner into the fuel tank. None of these things has made any difference. A week ago a code would come up like every couple days after a reset. Now the code comes back within minutes of reset. It has gradually gotten this way.
I used DashCommand to log some data, but I admit that I don't know the first thing about interpreting what I saw. Here is a link to an .lgf file. This data was at idle just after codes were reset. Near the end of log the code comes back. At that point the fuel trims go to zero and there are no more readings from the oxygen sensors. Anybody know how to interpret this data to help me get to a diagnosis?
