The car shouldn't have any problems since the motors in the P5 and the MP3 are exactly the same. The car will still run just fine and you won't through any CEL's since the ECU still thinks its plugged up to a P5. I'm ready to trade you when ever you want. In fact my car will be at the body shop until Friday. I'll overnight you mine and then you can overnight yours back to me and we will both be ready for the weekend. Call me...(336)688-2434
