Ok, if you don't have scan software, you need it. Check engine light? You need to log ltrims, maybe fuel injector pulsewidth. Do you have stock injectors and stock computer. You have a list of all mods ? stock maf?- if not, all bets are off.

WOT is when engine is at 100% engine load as per EPA,
PE can be functional as little as 25% on the gas pedal depending on RPMs and MAP value so PE is used a lot more then when in true WOT.
