Car runs horrible

well for a long while i was dealing with a a lean code problem on my car. code 41/91

found out after a while that my fuel pressure with the FPR connected to vaccuum was at 32 psi. with it no vacuum ;line connected to it was 41 psi. so i decided to drive around with the line not connected to the FPR with the line plugged and the code went away. but it drove fine.

but just now i decided to unplug the line and hook it back up and it drove the same as it was recently, maybe even a little worse.

then my starter went. got it replaced and about 3 days after that my problems started with the really bad hesitation. if you looked at the Tach you could see the RPM stay steady like a flat spot where the RPM dint go up when on the gas and then as soon as the power came back the RPM matched with the power and shot up.

i also changed the fuel filter.


i dont really know what a miss is but i thought this could be it??

so i got spark plugs ready to go in too. maybe with the lean codes it fouled up the plugs

and the car gurgles on de acceleration when it down shifts. sounds cool but dont know if really normal

no i dint check the TPS but i did think of that too. check that tomorrow

and my car is a Mass Air car

tps is at .81 volts
