Hey guys,
driving a 97 pontiac grandprix gt 130k+ Car woul experience a jerk/jerk/jerk when accelerating and especialy going up hill. Ended up being a bum vacuum modulator on the trans. Has a 3.8L 3800 series 11 in it. My buddy has a 98 olds delta 88 Ls with the same problem. I noted he also had a 3.8 with a 3800 series. My question is does his car also have a vacuum modulator as well? (Believe his car has 100k or so miles)
Any input would be greatly appreciated
