[:'(]'98 Dakota V6 4X4 86k miles. when cruising on the hiway, i'm getting an engine surge at around 65 mph. its not a miss, but the best way i can describe it is, you can feel the truck lurching as if you were feathering the throttle. under full acceleration it is not noticeable; only when at a steady speed.it's done it since it was new. the dealer said it was nothing. i kinda forgot about it because i don't do alot of hiway driving. but it is more annoying than anything else. by the way, my gas mileage sucks too!! anyone else have this same issue? -thanx
