just got my 3.2 out of the shop, had my throttle body replaced because my car was dying when backing out of a parking space. neway thats what the dealer thought it was, so it happen to me again today. when i back out of a space then put the car in drive it dies but only sometimes, i say 3 times a week. just wondering if any of u have had this problem and you could tell me what it is. i dont think it was the throttle body but my car is under waranty so let them replace everything for all i care. i have about 21k left on my ext. warranty
thnk u all...
