Took the spark plugs out and based on my years of wrenching, these plugs and coil wires were original. 15+ years and 170,000 miles. The gap was double the replacements, AC/Delco Iridium. They looked like something off the Titanic. I'm surprised one didn't snap off.
It ran so well on those shot plugs. Low throttle power is better now. I almost feel like I've got less top end but who knows, might be better low and mid-range deceiving me. Also found and replaced a broken ground strap. (headlights are brighter now). And I bumped the tires from 35 to 45 psi.
Might do a grill block next.
