My car has a backfire. I can't rev above 2000 rpm. I checked the MAF, changed the crank sensor, knock gauge, ignition coil, ECU, chip, and injectors. I have a Scanmaster and Powerlogger. What I see is wrong is the spark gap, which goes from 25 to 50 degrees. I guess that's my problem, but how can I fix it?
