P0300/P0302 Misfire code HELP ME!!!
Ok, so i guess im getting this damn misfire code on cylinder 2... im swapped out all of my plugs, still having the problem. I clear the light but it comes back on after awhile, the car stutters like absolutely crazy when im accelerating in 2nd gear until I get to about 3K rpm... anyone got any idea how I can get rid of this problem? Its killing my power to say the least.... any help ASAP would be GREAT!!!!

I have an SS/TC and I upgraded the intercooler piping and a 50/50 diverter valve. I took the diverter valve off yesterday and put the stock ont back on and it helped a lil, but now I can drive it just can't go sudden WOT or over 80 without backfires. And the backfires are smokeless.

Okay, will try that. I took of the 50/50 diverter valve and put the stock one back on. It runs a lil better, only sputters and backfires at sudden throttle, WOT, or over 80mph.

Change place coils and place spark plugs, but keep coming out fault in cylinder # 2
I have spark plugs NGK IX iridium I do not know the gap
Above says you should take AC DELCO 41-108 will you have to see?

But, these are the ones you should use? ACDELCO 41-108? and how much gap?
before changing to ngk I had this same fault because the spark plugs I had no longer served, change to ngk and it worked but 2 days ago the cylinder # 2 started to give problems (it is worth mentioning that the spark plugs changed them a little over a week ago)
