I need a favor from some one with a 93 or 94 Mark VIII. very simple while the car is cold like 30 degrees cold not 60, pull the plug off one of the injectors start the car and see if the Check engine liht flashes then goes out (the car should idle up then down)and the symptoms. it takes about 15 seconds for the light to come on flash then go out. I am trying to troubleshoot a problem and there are no codes. I think I have a bad injector or injectors after an engine swap. I would really appreciate the assistance. It should not hurt your engine as long as you dont rev/drive or leave it run for long periods.
