RPM hesitation on WOT?
Hey guys,
I'm still not sure if this is an ignition coil problem or a DI failure. No popping noises for me, had the P0351 code pop up a lot of times and cleared it a lot of times, it's just that it came up at high RPMs and didn't do any harm or show anything like the ignition coil is really faulty. But, now there's no CEL and whenever I go WOT I can feel the car hesitating like some sort of lag whenever under 5k RPM, and after 5k RPM the rpm goes up smoothly. Any idea? My best bet is the ignition coil giving away, but can someone explain to me the symptoms of a direct injector failure as to relating that failure to my problem? did it cause any mis-fire or hesitation on WOT when your injector failed?

you usually get firecracker/popping sounds with DI seal failure, often with no cel. |

No sounds for me, just the usual sounds of engine mis-firing with no backfire or anything, that feeling when it wants to rev but it holds itself as if you're letting off the gas pedal and then back full and so on.
