when i am light to mid throttle on my truck i get a sound that reminds me of spark knock. i dont like the sounds of it. i would ass-u-me, that injectors would fix the issue, but just wanted to inquire before i spend the cash.

Get a set injectors sourced,then remove & pop pressure & spray test yours. If your old ones fail test they are damaging the engine & wasting fuel,big time.. Read this on the Heath Diesel blog & heed!!!
