How do you check to see if your coil is going bad?, been running my street car at the Drags on test and tune night. been running fine except a lean stumble out of the hole, a re-jetting fixed that, but it started to "miss out" in high gear seemed to get worse every run. the coil is 17 years old (Accell HEI Super Coil) everything else in Dist is newer, was rebuilt by Suntuned a few years back, so i thought that would be the first thing to check. car sets alot, doesn't get driven very often, fuel system is new from this spring, #8 line, Holley Red pump, fuel cell, etc, cars best run to date 12.93 at 103mph, mild 406, Th 350, 3.90 gears.
