down on power

[1992hatch]

every once in a while when i try and speed up or take off from a light my car actslike its holding back but i can find a sweetspot where power not alot but power and if i shut it off for like 5mins its gone for a while but it comes back im thinking its maybe the maf or the cam angle senor or its going into limp mode for some reason but it is running rich when i put it on a dyno it was off the charts rich tell me what you think

I was having a problem when accelerating from a stop and after shifting. Cause of the problem was my forge divertor valve (plump back bov) was sticking.

i got ahole of the guy that sold me the motor set this is what i sent himquestion about the problem you were having with the engine would it when you tried to speed up it would boost but the car feels like it resisting then there is a sweet spot in the throttle when you just bearly push the throttle? and if so if it wasn't the wiring harness what could it be? but if i shut off the car for alittle bit it will go away again then come back ofter awhile

and this is what he sent me backare you kidding me? this is crazy. the only part that hasn't been changed out is the cam angle sensors, but those things never seem to go bad. i changed the tps, ect, knock sensor, fixed the o2 sensor wiring and it still had problems. i was just so sure it was in the harness.

can anyone think of a reason why the car would be doing this thanks in advance
