Hesitation at fixed speed (46MPH)
Hesitation at fixed speed (46MPH) I have had this problem ever since I could remember. I bought it used and don't know the history of the car. Almost everytime at 46MPH I feel the car almost bog down/hesistate then everything is normal again after. This never happens at any other speed. The only other problem I know that the car has is the left AIR pump with a crack in it that causes a squeeking. I have taken it to GM and they found nothing wrong with the car and couldn't even replicate the problem. Just my luck that when they drive the car it doesn't happen. Is anyone else have this problem?
What could cause this to happen at that exact speed? Injectors? I also threw in some gas-additive (Lucas) to 'clean' the injectors.
