General 7.3 Injector Question
I have a 97 f250 7.3 and recently had an injector start the trademark knock. The check engine light is now on and I have verified through a scanner that an injector needs to be replaced.
Basically, I just want a second opinion on the adverse effects of running a truck with an injector malfunction. A local mechanic told me that running this year of 7.3 with a bad injector with not damage the engine or any other components for that matter but will only result in a decrease of power.
I am moving cross country in a few days and am planning on fixing the injector as soon as I get there but if there is any possibility of damage, I will try to get it fixed asap.
Any educated opinions appreciated!

The only issue that I could see is that the failing injector might cause that particular cylinder to get hotter than the rest. Probably not an issue unless your towing/pulling.
It sounds like your pressed for time, but depending on how many miles are on the truck I'd look it getting all the injectors re-mand. If one fails, the rest are usually not very far behind.

Injectors typically don't knock when they 'go bad'. Usually they just quit firing and don't harm anything.
If there's a knock, then something is going on. A knock is metal to metal that shouldn't be there. Or possibly flooding the cylinder with fuel from a cracked nozzle which will soon burn a hole in the piston.
I hate to say but you need to address the issue ASAP.
