So I was working on finding the vacuum leak on the 95 Ferd. Hooked up the vacuum guage to the main outlet at the intake plenum. Running close to 20 inches HG at idle no climate controls on. Drops to 16 as soon as AC or defrost is selected. Plugged the main supply to the climate controls. Still does it any time the AC compressor turns on.
Uh oh. Not a vacuum leak.
Pulled #4 plug.(because I was right there tightenning up a loose manifold bolt anyhow).
Yep, running lean/hot.
Insulator is bright white. No carbon at all. Core is rounded. Electrode grounding strap is slightly c shaped. Gap burned out to .050" from .044".
Weak under load.
I remember now I timed it by ear last time.
Was gonna get a timing light...

.
I'll get a new set of plugs and probably a rotor/dizzy cap.
Then I'll set the timing with the timing light.
