Was driving around today, decided I felt like going full racekar on a side street, so I turned the corner, and punched it. At around 4500 RPM the car threw a p0068, went into limp home, no throttle response at all only coasting. Got to the parking lot, stopped turned off the car, started it and it was only running on 4 or 5 cylinders. Turned off the car, freaking out, cleared all the codes, checked vacuum lines, started it again, ran great, did a quick pull, no code. Still running fine. What happened? Did my car just go full retard or is there something wrong. I checked the MAP vac line and plug, both were in and good. Tbody plugged in fully. Anything else?
