from idle, if i hit the throtle all the way instantly. she stalls and almost dies. Cause?

 

Any backfiring? or just falls flat on it's face?

 

falls flat. There's some play on the dizzy mount. gona tightin that. if it still stalsl. then it's deff the head gasket

 

fuel mixture.
Let it warm up first. Does it do this while the engine is warmed up? Do you have the stock throttle or a larger throttle?

Could be the AFM

 

240SX throtle. and it does it when warmed up.

 

Check AFM / head temp sensor plugs... check your spark plugs... is it fouling out (running pig rich) ?

 

Might have something to do with running the KA TB on a non turbo motor. The turbo motors dont rely on the WOT switch of the TPS the way the non-turbos do. Just a thought cause I remember bleach saying he had problems with a KA TB on his NA a while back.
