sorry for the delay. i had the car flashed and was told that itll turn the limp mode off, which it did. i then drove it for about 35 miles or more and went to the deli for a minute and came back to limp mode problems. i was a block away from home so i parked it and its been for about 5 days limping with P 0520, which is a new code... i reflashed it to get it out of limp mode and got a new code...
