ok here it is when i get up to say 4 to 5 rpms the engine just drops i lose power when im on the gas to the floor and then when i let off and get back on it it just goes back to normal what is this why is it doing it its pissing me off bad

 

i mean 4000 to 5000 rpms

 

Any other symptoms?
There could be several things doing it.
Clogged cat? Need a new air filter? Bad power stage?

Wait for the experts to get on.

 

no cat not clogged the air fliter new the problem is the computer is killing my fuel injecters when i get up to 4000 to 5000 rpms in second gear or when i make the turbo put out more boost the car just kills the injecters again

 

also can someone please tell me where the hell is the map senor on this thing
