2000 gmc truck

My truck has a 4.8 engine with 196,000 miles on it. I've changed the oil every 5,000 and it has an occasional miss when I first start it up. It has 8 fuel injectors and I believe they need cleaning??? Should I put the gas treatment in to clean the injectors???
Does anyone here have experience with this problem?

Re: 2000 gmc truck

My initial thought is that if only occassional when warming up, would a dirty injector not act the same occassionally when warmed up?

Remedy in a bottle - may or may not help. I don't expect much from those - sorta like expecting the dishwasher to clean a dirty pan that wasn't scrubbed properly first.

Have you looked at or changed spark plugs lately?
