gst random misfire, sputtering

[97-gst]

I sent my coil on plug back to sparketech to see if thats the problem but its a hit and miss sputter. I changed my spark plugs thinking that was the problem and it drive great for 5 miles then it threw the cel random misfire and started sputtering the exact moment it came on. Idk what else it could be. Checked injectors, fpr, fuel pump, boost leaks, timing looks good, any thing else?

The random misfire... a dsmer's nightmare. It can definitely be a pain in the butt... i would think it could be as simple as a fouled sensor but I'm not sure I'd know which one to recommend looking at. Have you checked the fuses?

2 people I know can guide you better then me with immense experience in dsms:

1) Devin @ Boostin' Performance (tuner & builder) ....(630) 458-9600 chicago
2) Chris @ Mellon Racing (Big time Tuner)... (757) 497-1085 Virginia Beach

Definitely field your questions to them... i know them both personally and they can help diagnose you over the phone. Even better, if you have datalogging abilities, log the issue when it pops up, and save and email the log to Chris or Devin. That would really help.
