When I start my truck it has been idling rough for a few minutes and sometimes idles rough when I stop this has just started and I suspect I have a fuel injector that may be going bad. I have an airdog fuel pump that I installed earlier this year so I don't think that fuel supply is the issue. I don't want to take it to the dealer as it's out of warranty (80k miles).
The oil level has not risen and I am not seeing any additional black smoke.

What should I do here?

1. Buy a set of injectors, I wouldn't mind a mild HP increase.
2. Take it to a Cummins dealer for T-shooting.

Can anyone recommend a Cummins dealer in San Antonio, TX. that they have had good luck with.

Can anyone recommend a source for a new set of injectors that won't require me to mortgage my house?

Thanks in Advance.

Take it out and run it hard! Bet it clears up.
