Lack of power after just owning her three days.

[fosho92]

This is for a 92 mtx.When i picked up the SHO,it whould scratch third easy. Just driving her three days, I have lost about 25% power. Things were done befor i picked her up were: Compleate tune up including fuel filter, 60k service,new clutch,ect. Pulled codes got a 129,219. So I cleaned the MAF,no change. but when i unplugged it, got a slight miss but seamed to pull a little better. I know the other is SPOUT and could be the DIS. Going to try to find a MAF to swap out to check to see if it cures it. The other, possibly find another DIS. Anything else should i check?.The butterflies are opening at 4 grand I can hear them through the intake, and its mainly loss on the lower rpms.

So are you just saying it's lost power because it no longer scratches 3rd... or does it feel slower?

Feels alot slower over all.At first it felt like my old 1g Gst. Now it feels like a honda.
