I had a situation the other day in which I lost partial power intermittently and had a strong gas smell in my '94 NAS 90. I did some research which lead me to believe it was ignition related so I started going through the ignition tests in the workshop manual. I ended up seeing a pretty strong spark between the coil lead and the rotor arm, so I replaced it with a red rotor arm I had bought probably about a year ago, being all proud of myself that I figured out what the issue was AND had the part on hand to fix. So fast forward to yesterday, and the truck completely died right as I was pulling into a parking space. It started right back up though and I was able to get home. I repeated the coil to rotor arm test and saw the spark again so I'm hoping I just got a bad rotor arm. I have another couple of red ones on order but in the meantime is there anything else I should check that would cause the rotor arm to ground out? Thanks all!
