Trying to diagnose poor fuel economy recently (down 20%). No trouble codes. Checked all the obvious. How can I check that I'm getting adequate spark advance, just a hunch?
Also, when checking distributor pick-up coil resistance, the ohm reading displays momentarily, in a flash, it doesn't remain on ohm meter display. Is this normal?
have the same problem?
