check your part number to verify its the same. Even if you don't have a bad ECU, this is great to keep as a back up or for diagnostic purposes.As always with this type of component your best bet is to match the part number to the one on your original ECU. A faulty ECU is a common no start or random stalling problem with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. Low power & lean running are also fair game. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate. Comes with a 30 day functionality guarantee.
