Hope I am posting in the correct area... I just bought an 02 rodeo sport v6 4wd automatic. Everything seems fine for the most part except.. When I start it up and go to take off, it does this weird jolt almost like maybe a gear isn't catching? It only does it when I first start it up and take off then it's fine the rest of my drive. I live in AZ and it's 110 degrees on a good day so I make sure to keep my a/c off for about 5 min. to be nice on the engine but i'm not sure what the deal is with it doing this.. Any suggestions?
