Hey everyone, I did some searching and didn't come up with much. Since I got back from vacation last week and started driving my cobra again its been acting strange. The weather is colder than before so i'm thinking that might have something to do with my issues. about 75% of the time if I give it full throttle it will miss and buck. Seemed like detonation or spark blowout, so I changed my plugs with new TR-6's gapped at .32" thinking that would help, but the problem is still happening. I checked the codes today and it had an overboost code stored(but no check engine light on). It has never thrown this code before. I'm running stock blower with a 2.8" upper and a custom dyno tune. I had it tuned before last winter so I drove it through last winter without this problem and I haven't changed anything engine wise since then(other than the plugs i just changed). I don't have an a/f gauge or anything but the boost stays steady it just misses/detonates under full load. 80% throttle or less the car drives perfectly. Anyone have any ideas? Oh i changed the FRPS about a month ago too because it blew out. All the old spark plugs i took out(which were also TR-6 looked just fine)
To me it would seem like a tune issue but i have had the same tune and not changed anything for like 14 months so why now is it doing this? The fuel pumps and injectors are all stock too. Oh and the fuel filter is fairly new too-like 8 months old. Any ideas would be greatly appreciated! Thanks!
