did a wheatly tune (had the rear 02's deleted) and headers about a week ago and had no problems, until sitting at a light the other morning starting idling a little rough but not to noticable and but ran fine other than that,then got the p0300 a day later checked the TB, plug wires, and MAF and swapped to my stock computer and it doesnt seem quite as bad but its still there, waiting fore the light to come back. so i guess whats next?

 

so the light is on and its still idling rough,(CEL did start blinking but then went back to solid,)is it ok to drive like this?, ill probably change the plugs tomorrow and see if that helps

 

pull all the plugs out and inspect them. You may have damaged one on the header install

 

when doing my headers we did drop a plug but checked it out at the time and it was fine, went to pull the two we removed for the install, took the wires off and the protector sleeves i have on them and there was a small burn mark. i barely bent it and the wire pretty much came to pieces so i changed both plug wires and i think its cured. now to find a way to keep the wires off my headers, what are you guys doing?

 

Taylor wires will fit around #3 but you will still need heat sleeves. Figured it out after burning 2 sets of wires.

 

weird your burning wires I've got edelbrock headers on and OEM wires no heat shields or nothing and never had a problem
