How do i clean fuel injector without removing the injector.

Have you cleared the faults? How often does it happen?

 

ok, whatever you say..

that's like the guy that never changed his ATF fluid for like 100,000 miles, then does, and KA-BAM......transmission acts up, as all that built up varnish that was protecting the bands and clutches wasn't there no more.

gotta get things when they are new.

but, you do you.

 

You said you "keep getting codes". So light is coming on and going out? Or the light was off once and came back on?

 

Troubleshooting literature..Not sure how much this will help.

 

My last boss used ATF every time the fuel filters were changed.

And about once a year. The truck would run a little rough. 2 gallons of that centech or super tech or whatever from Walmart. In each tank would fix it up.

I don't know about Cummins but the cat motor I was running had issues with the electrical connectors. Coming lose or something. I was never told what was going on. But it was an easy fix. When it happened. Which wasn't often.

Cummins injectors are always causing problems. They can’t seem to get that figured out. I had a factory rep tell me 25 yrs ago they fixed their injector problems. Lol. It’s like a plague.
