[QUOTE="Steeda30, post: 7623956, member: 23794"] The reason it was sputtering and acting up at high RPM's but driving fine normal was because the ground strap on the plugs were melted back, effectively increasing the gap beyond the limit that it could still fire effectively in a high RPM/boost environment. Mine drove fine on the way home after I melted them, but it'd miss and stutter if I tried to boost at all, spark was being blown out. I didn't have the oil problem, but I broke the porcelain off of 4 plugs on my stock motor a few years ago. Here's what the aftermath looked like. The engine ran fine after it happened for several months, it burned oil in #7 though, and the leakdown/compression was a bit down, but not much - it still made 502 RWHP. I finished it off one night with WOT pulls with no coolant in the intercooler fluid reservoir, the hose came off while I was driving at some point and I didn't know it, so #7 was finished off, and that's when I rebuilt it. What you're seeing on the plugs is a sign of severe detonation. Mine was caused by air pockets in the coolant, causing excessively high cylinder temperatures at WOT which resulted in detonation. [IMG]http://www.03svtcobra.net/CobraTune/CobraBrokenPlugs/Plugs1.jpg[/IMG] You can see the nicks on the right side of the ringland caused by the porcelain, it will ding up pistons. [IMG]http://www.03svtcobra.net/CobraTune/BurnedPistons/Piston73.jpg[/IMG] I hope you got lucky and it and didn't melt anything in there. Get that compression / leakdown check done. I know how you feel, it really sucks :( Did you ever double check the tune on it? What kind of A/F and timing curve? I see it was done with a mail tune from Rick, are you sure he got all the data he needed to make the tune? [/QUOTE]
