HELP - Codes
I was driving my car hard today. Stomped on it in 2nd and power cuts off. The car is still making boost and drives normal. But the P0102 code is on. I tried reseting it and after I restart the car its on again. Is this a blown MAF?

I'm sorry, I shouldn't have done that. You're thread title reminded me of it. It's a code to an original Nintendo game, I can't remember which one, but that code seems to be stuck in the head of anyone who ever had a nintendo. You're about my age, if you had a Nintendo, you'll recognize it.
