Hi guys. Been having a few dramas with my 96 Fairmont recently.. it seems to be activating the knock sensor or something and i cant pin point whats causing it. As the cars accelerating is makes a sound similar to that when hitting a limiter, stops accelerating, drops revs then picks up again and does this about three times. I've noticed it only does it on one particular stretch of road and i'm stumped as to what it might be. I initially thought the box was slipping but i've since had that checked out and everything is fine. Any ideas as to what it might be??
Just for the record i ran the car on optimax last week and didn't have a problem. Any help will be much appreciated
