1991 idles fine,when increasing throttle it surges and will not gain rpm
just finished putting water pump and cam belt on, car ran fine before, now it starts and idles great but surges to gain rpm, but will not rev higher. recent new fuel pump and fuel filter
if it started doing this immediately after a timing belt change, i would assume the timing is a half tooth or more off.
agreed with other poster,timeing is off to low.
