Hi everyone, so I might have gone the long way around, but I recently had the engine light come on. When I had it read it said random misfire. Thinking I could eliminate it, I replaced plugs, injectors, coil packs and yet I an still getting a mild hesitation during driving. Weird thing is, if the car sits for a couple days, the engine light goes away. Thoughts?

 

Are you consuming any coolant? Or pushing any out the overflow?

 

Not that I know of. The water levels are always full.
