what are the signs of a bad map sensor?
well the vp44 has about 25kish miles on it.
always had fass system on it. 15-17psi and 70% Of its life was with 2 stroke
it kinda hestiates from a stop. sluggish then power comes on nice. im not building alot of boost either. 5 poundish. so i dont think its turbo lag.
in 4th gear ussualy around 2000-2100 rpms under WOT it feels like it falls on its face.....no power, like no fuel basically.... fuel psi is good. also. if i let out of the throttle then get right back in it. the problem does not exisit
also it lopes with the a/c on when putting the clutch in and letting it fall to idle
it will dip about 200rpms under idle then even rite back out.
or possibly another vp44?
i have cleaned my map twice before so i dont think its clogged
truck did have a smoke switch on it for quite some time.
i just reset my apps. going to see if that solves my problem.
i also have no CEL on. and no scan tool to see if there is a code...
as far as my knowledge the symtpons show one of the 3 components are bad...
only other one i can think of would be ecm.
any help would be greatly appericated.
