Ok here we go. The check engine light is unrelated to my issue. Apparently the emissions guy didnt put my gas cap on correctly. I havent gotten gas since i had my emissions done last week. Check engine light was a result o a major evac leak. The gas cap. Ugh feels so stupid.

Anyway, cant figure out whats causing the jerk. Mechanic says everything looks good and no sensors ate throwing any codes. He doesnt know whats wrong and until it becomes more than an occasional problem he says not to worry about it. It may just be a characteristic of the trucks age and mileage.

So ill just wait and see i guess........
