As reported in a different thread, I recently went through the ECM reset procedure....... worked great, sorta. I still am having a real stumble off idle and a bit of the black smoke with throttle. Any other ideas I should check out? I may be able next week to take it to a dealer and have it checked out...but, would like to fix DIY. This is the only snag with the whole fuel injection thing....hard to change or alter w/o special equipment. Again if you have any suggestions, I am more than ready to listen.
