Now i dont know why the hell this worked... but i got an engine rebuild with new apex seals and whatnot... and no longer does my car backfire. The mechanic told me that there was an exhaust leak, and perhaps that caused it... as well THE TIMIMING WAS PROBABLY THE BIGGEST FACTOR AFFECTING BACKFIRING AND POOR MPG!!!!!!!!!! A stupid stupid 20 minute job. How very foolish of me not to do that first. Apperantly, the ECU does not do a very good job of properly adjusting the timing. But then again, I am an idiot.

 

yeah well you have anew engine to play with now :-)
