My truck 5.7 Vortec has a slight misfire at 60 MPH and 2000 rpm and steady speed. No codes. No miss under slight speed increase or heavy throttle. Repaced cap and rotor last year, and ran injector cleaner, fixed it. But now it's back, ran injector cleaner again, no fix. Ideas?

Have the injectors cleaned by direct injection of the cleaner to the injectors. Additives rarely work, you need full concentrate
