Bad Injector No code

I think it would be possible to have some codes that don't light the CEL but are still there. Since I got my AE software I have found that there are many codes that don't show a light. Also most injector codes are electrical related not to deal with poorly spraying nozzles like your symptoms suggest. You could try to over treat your fuel when it is low like 1/4 tank with two cans of sea foam. Don't get too crazy or you could damage your engine. I did that while my injectors were not in the budget and it helped. How many miles are on your truck? Can you change your own injectors? If so you might just want to change them and get it over with.

Have a good day.
