1993 Silverado 2500 6.5 Turbo Diesel - Missing?

The truck has 200K miles on it and runs generally well. Fuel filter is fairly new. I noticed today that at idle it seems to be missing. Anything in particular that would cause this on a diesel engine? Would an injector cleaner for diesel fuel hurt anything?

Thanks,

-Steve

BTW, it's not a steady miss... It's just kind of a slight miss randomly.

You will be lucky if you don't have some cracked heads or other major mechanical wear at the mileage. If you can live with it, run it until it dies. It will cost you big bucks when it does to rebuild it.

While I'm sure the engine does have a fair amount of internal wear for the mileage, there is nothing severe liked a cracked head. Compression is is perfect all around and it has plenty 'o power and is smooth as can be when you are at anything above idle. Despite the mileage, the entire truck has been taken care of and is just about as pristine as you will find. (Always had regular oil changes, filters changed, etc) While it has been used to pull a goosneck trailer much of it's life, it's still a nice truck (Ex cab, power windows/locks, everything works, leather seats, clean carpet, no cracks in dash or door panels, etc etc..)

I'm suspecting it's just dirty injectors. This "miss" is definitely something you can live with because it's ever so minor. I mean, it's just a "blurb" every now and then in an otherwise smooth and even idle. The truck has absolutely superb performance otherwise. I'm sure most people would never even notice this "miss" I'm describing...I'm just anal. lol

I'm really just curious to know whether or not a diesel fuel injector cleaner would do more harm than good?

The miss at idle is most likely a worn injector that is leaking. At 200k mileage this is normal. In fact my Benz is doing the same (at 270k) so I'm sending them out to be rebuilt. There is no fix in a can for this.

I suspected it was going to be time for injectors to be serviced or replaced.
