Hello, new here. Just bought and registered a 02 4wd super crew. 142,000k.Test drove it two hours yesterday with no problems. Bought it registered it today and low and behold it starts to "skip or what you would call buck when driving. Of course the "check engine light" is on. I call the local stealership and now I think I'm regretting buying the truck. The service history of the truck is very good. So any comforting words or suggestions would help me sleep better tonight.
