Did you buy the correct BCM? Your Cardone part number is 73 1754. Rockauto.com shows it in stock. No programming is necessary! It's 100% plug and play!! Hope that helps! Jim

yes, this the part number of the BCM that i bought, should i try to buy a new key , and where can i get a new key?
No, don't buy a new key. The new BCM is now mated to the key that you have. Your ignition key has a visible chip on it, correct? Jim

do i need to replace the ECM. the car is now stalling and when i press the gas it will accelerate slow, then when it picks up speed it jerks when changing gear. i have to keep pressing the gas to make it accelerate to pick up speed. the fastest speed i can get to is 64 miles
