Hello everyone. Have misfire problems. No codes Engine light was on at one point. Changed plugs and coils. Still misfired. Changed injectors. Still happening. Read that the rocker arms or rollers or whatever they're called could break loose. Pulled valve covers. None broke. There is a ticking at start up but does go away after a few minutes. Vehicle has about 250k on it. Im at a loss on what to look for. Start over and check connectors to coils? Could it be a roller that is maybe starting to fail causing it and the ticking is a warning sign?
