Good bet it's your maf. Check the wiring and all grounds. It just bounces at 3k right? Almost like a limiter?

It's tight? As in the wiring and all your grounds? The sensor itself could also be bad. That's what your symptoms sound like to me anyway. Get a multiple-meter.

^^ what he said MAF may have gone bad, but then again harness might have funky wiring. You need to check resistance with a multi-meter.

... hehe. "multiple-meter", first time I hear that. :p
