We had it scanned yesterday, and no codes came up. Took the maf back out and cleaned it again a little better, still no go. Checked the timing which appeared to be off. I re-set it and it still doesn't want to rev.
When you soft rev it to around 4500, it acts like it has a limiter on it. If you put the gas down more, the limiter drops about 1000 rpm and you can hear the car working harder. During this you car hear the exhaust popping like it's misfiring? (sounds like it has an aftermarket intake - but it's stock) It's all very weird. The car had the timing chains replaced not too long ago, but is making a lot of racket like the tensioners are still original.
edit: I can say that the more you drive it, the limiter starts dropping to lower RPM's. If we clean the MAF, it raises it back up.
