After a long week of driving (1000+ miles in 8 days) my 98 cobra with 54,000 miles on it picked up a rough idle (feels like a miss), has had a drop in gas mileage, and the last time i got on it, i thought i heard some detonation, and around 5k rpm at WOT it felt as if I hit a wall in acceleration. The exhaust tone changed and i lost so much power.(Felt like i hit the rev limiter at 5k) I ran it again up to redline, and didnt hit that wall again but power does seem down still. Im afraid to run it up hard because i dont want to cause anymore damage. I know its not bad gas because ive gone through 4 tanks.
What do you all think is my problem? Ideas, suggestions? Thanks!
