Well...after getting my car running not so rich. Now...when I hit about 2,000 rpm it hesitates and will buck. Like it doesn't want to go further in the rpm range. But if you give it more gas it will get over it and go. I guess it only happens under normal driving. If I'm at a stop and rev the car up slow it will bounce at 2,500 rpm like the MAF is unplugged. But if I give it alot of throttle it will go past 2,500. I'm not sure what is going on. The car idle's perfect, there's only one vaccuum leak and it's for the brakes booster. I haven't hooked that up because the line is crushed for some reason on the intake manifold. If anyone could help that would be great.

Mods are:Stock motor, except for a HKS Wastegate kit.Z32 MAFSAFCII

Edit.After thinking, I do remember that the SAFC isn't reading knock. The knock wire may have come un-done. Could this cause the problem?

Do you have any way to monitor your sensors? Voltages or percentages?

I'm going to try this. Now that I think about it, it makes sense. Hopefully this will fix my problem.
