| Ok so I took everyones advise below....To begin with my 91TT suddenly was missing on cylinder #4 about 10 minutes into a drive. Applied di-electric grease to all PTU/CAS injector and coil connections to alleviate the problem since this has fixed it in the past. Nothing. #4 is still out. Drove home and it came back suddenly running smoothly. Started it in morning and #4 still isn't going. Soooo... I swapped Coilpacks/sparkplugs from a known good cylinder and recleaned all connections and #4 is still out. So I took a long screwdriver to my ear/injector to hear if the injector is clicking and it is not. All the others clearly are when you put the screwdriver up to them/ear. So am I looking at a dead injector? Considering this is only occuring on the same cylinder no matter how much i clean/grease/jiggle wiring hardness etc, I don't think it is an electrical issue. Any input on that? Also, is dremel method any easier/harder on #4?? I think I'd prob pull plenum, but I'd be willing to give the dremel method a shot. Thanks
