Well, here's my problem. After reading and searching, combined with multiple attempts at repair, I have a misfire code for cylinder #1 that won't go away. I've replaced coils, plugs, switched plug manufacturers twice, checked the common things ( leaks, tears, loose clamps ) and changed gas stations. My car has a Cobb SRI, Forge BPV and exhaust (cat-back only). I intend on re-setting the ECU after putting the stock parts back on, but before I do that I don't want to waste time and possibly have the same problem, and I can't justify swapping plugs and coils time after time. The car averages around 25 MPG, runs and drives fine until WOT higher boost situations, then it begins to sputter and pop through the tailpipe combined with the overall loss of power... driveability shows no other issues. I don't have a tune, no Dashhawk, but I have a scan tool that lets me see certain parameters in real time. Any suggestions as to where I should go next?? Thanks in advance!
