Default So I had my car dynoed...

I was running lean 15's and a multiple misses at high rpm. So where to start to look for problems? The usual bolt ons etc., wait4me tune. Car runs good on the street,mileage is so/ so, rear 02 are gone/tuned out. high flo cats . Tuner said disconnect MAF and see what happens while driving. Car runs well with the maf unplugged,shifts are REAL hard.

02s?
Maf?
Plugs?

I did some more research on the subject and someone suggested to do a test to see if it's the MAF where you unplug the MAF and wait for the computer to realise it's not there (which takes like 10 mins of driving) then gun it and see how the car reacts. If it's better then the MAF is the problem, and if throttle response stays the same, then you need to keep looking for the problem.

Fuel pressure check is next. I cleaned the maf real good. It had black soot on half of it. Cleaned, re set TPS and reset pcm. Car runs much better so far.
