P0068 - Throttle position not consistent with Mass Air flow sensor
« on: September 16, 2011, 12:30:43 PM »
Going to lunch today, backing out, slightly uphill, curve on one side, pickups behind me so I was at an idle.  And of course I stalled.  :(  Cranked it back over and it sputtered but did not start.  Tried again - nothing.  Third time I floored it like it had a carb and was flooded - bad mistake don't ever do this at home.

Fired right up and then started running like it was on 2-3 cylinders, could not clear it, no power nothing.  Got out of the middle of the parking lot, shut it down.  Restarted it normally - same issue.  Tried again, no improvement.  Went to the diagnostics mode on the dashhawk and had a P0068 code, to clear it I had to shut the motor off.

Cleared it started the car and it has been fine since.  Leasons learned:

1.  Don't stall the car


2.  Never ever touch the gas on a computerized fuel injected car when you are starting it.

That's what happens to me if do a rev & release at idle. I think it has to do with the supercharger rapidly shoving large quantities of air, then the throttle closes and the maf/map sensors are still sensing air flow and or pressure.

Shut off, clear codes, restart, don't repeat.  :)

LMAO.....I would've too! hahahahah

I'm laughing, but...not funny really. It's a big deal when our cars stall and even worse, when they don't want to start.

Enjoy the weekend. :)
Ride it like you mean it.
