Re: 88-98 FAQ's "Is your truck running weird? Check here it could help"
Great info chevytech. I have a question for you, I have a 98 W/5.7, 4WD, 1/2 ton. The problem is it stumbles at higher speeds when climbing an incline. Example-Driving on the highway at 70 and start to go up a hill it wants to stumble/shake as its trying to downshift. This happens whether I'm pulling or not. Your help is appreciated.
