I've changed the cap and rotor, as well as the wires. The timing light doesn't go off on #1 about 85% of the time. I know from checking o my other vehicle that the light will flash even if you don't have the wire connected to the plug, so it can't be a bad plug. For some reason, the distributor isn't sending spark to the #1 cylinder. The only thing I may have done is to try to install a mileage gauge which required tapping into the #1 fuel injector wire. I never did get that thing to work right, either. I will, one day, though. Then we'll see what kind of mileage I can get. Anybody have any ideas. Know where I can get a wiring diagram to try to figure out what could be messed up? Thanks, Gas.
