HELP! Engine very rough after start up.
Here we go again. This truck is going to drive me crazy. All was good till today when I started the truck, drove about 6 blocks and a rough engine, no power started. All my fluids and filters are good and up to date. I recently did my under valve cover harnesses....both new. Changed out my cps before posting and checked all the wires....and still I can start the truck, runs fine for 30 seconds and starts the rough idling. No engine light comes on and I do have tach working........ Where do I go from here?

If it feels like it's running on 7 cylinders I would think a loose armature.
If it shakes real bad and has ZERO power then I'm thinking a whole bank of injectors is out.
A buzz test is in order or you may have to pull the VC's.
You could always try the infared thermo on the exhaust ports and see if you have a cool cylinder.

Cleaned the connector real good prior to start up.......started up, ran find 30 seconds, started with same rough idle. Turned off truck, changed out computer to the stock one I had....same thing. this is really driving me crazy. Truck has 68K babied miles with numerous upgrades and I get this shi...........t. I guess I need to drive the living **** out of it. I really dont want to take it to the dealer cause its going to run me an arm and a leg........Guy, need help here.
