My symptoms were mild. Every once in awhile, under WOT, this code would throw, causing the half engine light / limp mode to come up. For me, it only occurred occasionally under WOT like after 10-20 mins of continuous redlines (aka on the track). For more serious cases, some people have reported it triggers everytime they go WOT.
Basically, you're accelerating hard, it triggers, and you go into limp mode until you reset your car. Nothing else happens. Sometimes, it would cause misfires, and your car would shudder until you pull over and reset.
