I spoke too soon! I was checking my sparkplugs the other day looking for the cause of a miss at idle and had removed the coil to access the back bank. When it was time to put it back I decided to put my old coil back and "save" the new one. Well,on my drive to work the next day, 38mi., It was stumbling much worse!! I apparently have multiple problems! Aarrrgh!! I wonder if I might need injectors after seeing the crap that was in my fuel rail. Is it possible for crap to get past those tiny arse screens in the injector inlets?? There was plenty of crap but I don't think it could have gotten past the screens and harmed the injectors! Man, this car is driving me crazy!
