ka bogging at 3k?

[murderrsirenss]

OK, when im driving and I hit the 3k-4k range my car just starts bogging and acts like its not getting any air as if the maf was unplugged or something. I have replaced the o2, and cleaned the maf twice. Ive listened/looked around for a vacuum leak, but dont really see anything. I have also filled it up with gas and added heet water remover to make sure there was no water in the gas tank.

Any ideas? I tried to make a video with my phone, but it was horrible so im not going to bother to post it.

Check TPS voltage, perform sweep test.

maybe wires? cut the car on at night in a very dark area and watch for arch.

Well I just cranked the car and unplugged the maf and the idle raised a little then went back to normal, bad maf, correct?

I think that's just limp mode, I could be wrong.

Have you tested the MAF? Also there was a TSB on it a while ago, add an extra ground for the MAF.

Anywhere is fine, body or intake manifold works.
