I'm at VIR for day 1 of what should have been a great two day event, but I've been dealing with an unknown gremlin. I have absolutely no power and no clue why. No new codes have been thrown. I say new because my O2 sensors have been shot for a while and they are the only codes. I never go into limp mode, I'm not leaking anything, and nothing mechanical appears broken, but the car literally falls flat on it's face at about 5,000 RPMs. Basically I'm running about 1/2 throttle and my left arm is getting a serious workout!

Car ran great for the first two laps this morning and ever since it's been a disaster. Last track day was a month ago and the car pulled strong all day.

At idle all sounds fine, but as soon as I get on the gas the engine sound changes (gets deeper), car begins running rougher, and is just dead. I'm assuming if I was down a cylinder I'd be throwing codes. No? If anyone has any ideas I'm all ears.

If I didn't know any better I'd swear I got some bad gas, but everyone has been using the same pumps as me.
