Well, one and a half hours later, the coils are in. I must not have messed it up as it idles smoothly and there is no Check Engine Light. Problem is, the hesitation under hard acceleration is still there, like it is hunting for something. I then did the SeaFoam treatment into the intake per the instructions and then dumped the other half of the bottle in the oil so possibly help with anything funky going on with the cam phasers. After the 5 minute wait time, i restarted the engine and it ran a little rough, revved it up some and it got a little better so i decided to take it for a spin. about a half mile down the road, i goosed it and it seemed to clear out the remaining roughness, but then the check engine light went on right about then, I disconnected the battery when I got home and restarted, the light stayed off. Hopefully it will stay off. Anyone else have this happen to them?
Also, it knocks when you press the pedal quickly at certain RPMs, Could there be some sort of throttle position sensor or the actuator for the throttle that I could look into for this?
