ok yawl here is my problem
every once in awhile after driveing a few miles ill come to a stop at a light or what ever and the truck will start shakeing like a gas engine does when it is missfireing. ive plugged up the tesh 2 here at work and there are no codes in this damn thing. what do yawl think it could be because it dont happen all the time.

 

you can check the #5 and #7 injector connectors just to be sure and make sure they're connected solid.

when was he last ff change

 

about 3 weeks ago ive put about a 1000 miles on it since then.

 

I believe #2 and #7 harnesses can be problematic..

Here is a rundown of another members issue, that I believe is related to yours.. and a quick fix too
