So I’m currently at a loss with my car. I have a 99 Cobra with an 04 Terminator swap done and it’s damn near perfect. The car idles and drives fine without a sign of any issues but when I go to open it up in WOT, the car falls flat on its face at 4000 rpms. It reaches 4000rpms and begins to buck and jerk until I let off the gas. So far I’ve changed the air filter, cleaned the MAF, changed the spark plugs, and changed the fuel filter. Has anyone had any similar problems and if so how did you fix it? Thanks.
