2nd gear WOT car hits a wall
Well I have searched the older threads but have not found a solution to my issue.
When driving in 2nd gear WOT it will put hard, full boost, until I hit about 5100 rpms at which point the car hits a wall, it throws me forward and feels like the gas pedal goes dead. Doing some research on other cars having this issue I have come across ideas such as bad plugs/wires, fuel cut, fuel filter/pump. In first gear and third and fourth gear it pulls strong all the way to redline. Anyone else have this issue on their cobalt or have any other suggestions/ideas?
I do get a lot of crackling when driving from the exhaust, every time i hit this wall i quickly let off the gas of fear of back pressure. I know when i had cobb stage 2 on my STI it required a header as well, anyone think that a full unrestricted exhaust might help?
