about 3 weeks ago i regapd the plugs to .9 because it was missing, poping banging a little, under really hard load, and that fixd it, but the othere day i took the car upto about 180 with 4 people in it, it didnt somthing really weird its an R32 GTS-T auto it got to about 7700 rpm and the engine sorta lost power for a second then came back in again, like it had a rev cut or somthing?
now when i plant foot it starts poping away missing all the time, have no power at all......?

Thrashing Toooo Hard..

7700rpm?!?!? shit.. I barely see 7000....

When it hit the Speed Limitier it isn't possible to maybe blow off some sort of vacume hose is it?

Yeah the AFM cuts because of the strain on the engine, 7700 in 4th is over 180.
My car does the same thing, and I was told it is the AFM and changing to 5th will sort it out.

As for the problem... maybe you killed the AFM again..?

Ben

i pulld the inside of the cat out a week ago, could that change a thing?
how could the AFM make it detanate and miss?

doubt it.

You didn't mention it was detonation and missing..

reset the computer and see if that makes a difference

r u running extra boost? and does it do it more on a warm day?

cause my gtst was doing the same and i regapped my plugs to .9 and that sorted it but it still pops a little at 12pound and i think its cause the intercooler isn't up to the job (its sweet at night when its cold)

just my ideas anyways

You've probably just stuffed a plug, or maybe fouled one (or more) up a tad.
Pull 'em an give them a once over & a clean, then see how it goes.

Although the 7700rpm bit doesn't sound good:( what's up with your rev limiter???

i dont know.... i think maybe the oil in the auto is stuffd.....??
its been over reving since i got it.
