HI, I have a 1998 chevy 2500 silverado with a 5.7 350, this truck starts, idles, and drives fine, but when you go up a pretty steep hill the transmission will downshift like normal and a few seconds after downshifting the dash and steering wheel start to vibrate and shake. The engine will start to lose power and backfire, a few seconds later it will come out of it and be fine until the next hill, I have done a complete tune up, but the problem is still there. I pull a gooseneck trailer frequently and it is a real pain.
have the same problem?
