Hello Mr. McGee,
We are very sorry we could not meet your expectations. If it was possible for us to check into the engine light issue we would. As you already know the car has some aftermarket wiring done to it previously. The aftermarket alarm system in particular is hard wired into the ECM. This is causing us not to be able to communicate with the car using a scan tool. Please let us know if there is anything else we can do to try to help you as you are a valued customer.
Thank you for the kind words. We strive to keep our level of service as high as possible.
