deanyel, I have never had any lights appear or I would have dealt with it. I do not leave things go. But, this is Florida, it is very common practice for mechanics to disable lights to hide problem indicators. I will make sure all indicator lights works. I have never had any performance problems to indicate a problem. I have only had an occasional rough idle, that I assumed was an injector/injectors issue from infrequent use. I had planned on either cleaning or replacing the injectors. Also, I do not think the engine suffix will hamper my efforts to properly obtain parts, which has been one of my concerns. Before removing the engine, I was assuming a 104.980. Thanks.
