low injector control pressure
when i get on it my check engine light comes on and it throws a code for icp too high or low. i can get it up over 2800psi on stock but if i have it turned up and mash the throttle i can only get about 1900 or so. i can get up to 2500 with about 1/4 throttle though. its not smokin much at all,so i'm thinkin it might be fuel pump related? i don't know what the normal readings are for fuel vollume desired and exhaust back pressure if it might be defueling or somethin. it didn't do it nearly as bad when i first got my chip but the light did come on but it still ran good, now it just doesn't have the power it should when i get on it. it runs great part throttle most of the time, so i don't know if it could be the icp sensor or ipr lift pump or what. any help would be greatly appreciated, i have a goat to slaughter. the code its throwin is p1211
