2G Sputter/Misfire on highway.

[JMiller]

I have been going back and forth between NC an SC every few weeks and its about 130mi. When i get on the 77 south/north and drive for about 5 min at 3000rpm in a 50/50 vac boost condition when i got WOT it stutters real bad for a few seconds, then runs good for a few seconds, i shift to 4th and it does the same thing just not as severe, then i shift to 5th and it barely does it.(i cruise for the first few minutes then got on it). I also have a random misfire at idle sometimes. I run BPR7ES plugs gapped a .28 and i had my CEL checked a while back that said misfire in cylinder 3. I pulled my plugs today and cylinder 3 had brown dust on the outside of it and the top of the plug/inside of the boot had a white powder like residue. Could my plug wires be what is causing this.(Mods in profile are up to date) Thanks.

hey man it looks like alot of upgrades for you to be running stock fuel management. you might want to look into dsmlink. cause it seems like you need a tune.

I wont be able to get any major upgrades like fuel setup(Apexi Neo, 650 inj, AFPR, etc.) for awhile. But i did come across something, when i pulled the #3 plug wire, the connector wasn't completely on the plug(actually not sure if it was on it at all) so i pushed the connector closer to the boot/bottom and it made a CLICK sound when i re-installed. When i Test drove it, it seemed better but i can't tell for sure until i get back on 77.
