Talking Re: no throttle response
Again Again, been there and done that........

I was autocrossing and had this issue when going hard, not spinning, just hard like 6000 in first for 40 - 50 seconds on the course. Drove me nuts and it was before I got the data logger, Zeitronix which would have shown the real issue.

I opened my throttle pedal and throttle body looking for issues and it was high inlet air temps due to poor cooling of the innercooler. This what spun me into the cooling mods for the car, super cooler, hood vents, insulation blanket and engine lower pan deletes, separated I/C c/c Brian Brave and lower tstat mod (180F).

You need to go hard in second from a roll so that spin is eliminated, and see if the error occures. IF it does it may be poor cooling of the I/C which may need a radiator flush and new coolant. My I/C had a waxy gunk in it which I flushed and got rid of to assist in my problem.

Heating can give you the errors noted and they may take only 15-20 seconds of WOT to occure. If its wheel spin, you should see the TC flash and NOT set fault codes.

Like I said, I went nuts and started opening all the modules to see how they worked and clean them which turned out to be unnecessary. Fault codes are a starting point and not always correct per se.

My GPS actually send me in circles at times and has me loop - so dont trust electronics too much or all the time. Pacemakers are the one exception . . . . . .hopefully
