1998 4.2 Automatic
If im going down the road accelerating at a pretty slow speed and i dont change my foot pressure on the pedal. It seems like right when it shifts into 4th the engine races pretty loud then kicks in. The truck kinda lunges when it kicks in there going down the road. I thought maybe I didnt have enough vaccum pressure or something going down the road and might have a link. What do yall think?
