Archived #1 Cylinder Missing.... Need to leave but unsure.

[KBalzuweit]

I just started the truck to move it and it was missing pretty bad. It ran fine yesterday on the way back from Wisconsin. I used my point and shoot thermometer and checked the temps on the exh manifold. The front cyl was 130 and the rest were 170-180 at idle. It seems when the rpms come up the miss is better?? but after it goes back to idle it just get worse. BTW I put it all back to stock and its the same. HELP!! I am thinking injector?? Maybe?? I have 70k so I am still under warranty, but if its not rolling I'm not making money. Plus I am dispatched to leave and take a trailer to Colorado!

Sounds like maybe a bad load of fuel got an injector. Being under warranty... I'd take it for a drive to see if it cleared up. If it does, take the load. If it doesn't... well it is under warranty... but I'm not sure what your penalties are for being late, or just not being able to take the load... .

What gets me is it was fine when I shut it off last night. I put on about 1000 miles since I filled up too. Never through CEL and there are no codes.

I would try running some injection cleaner through it see if it gets the injector working again.

The electronic gizmo(valve)mite not be working. So the inector mite need replacing.
