I am also experiencing P0351 CEL.

N/A, EcuTek Tune, catless header & midpipe
Tracked the car in June @ Sebring for the 1st time.
On the 4th of 5 sessions the code came up. Cleared it with Ecutek @ the track and ran the 5th session without recreating the code.

Tracked the car again 10/11, after the warm up session it came up once again.
I went ahead and cleared it and it came up every session throughout the day.
The car appeared to be running fine, AFR was in range...

Car has 40k miles & only 2 track events...

From what I'm reading, I think I'm going to try new plugs & a new OE coil...
Probably take a spare with me to the track...

I like the idea of the Aluminum ECU bracket, will probably try that out as well...
I will post my results...

Seeing how the exhaust is only a few inches below these 1 & 3 coils, I'm going to try a pipe shield, found this:

I am however concerned about the injector issues, but I haven't encountered any fuel or injector DTC's...

Thanks
