1990 Pontiac Grand Am LE 2.3L Waste Spark?
This vehicle intermittently has what appears to be ignition spark at the front crank pulley! More precisely 2 snaps at the 10 O'clock and 2 snaps at the 2 O'clock positions. No apparant misfire and no tach needle jump. Not familiar with this system; any ideas ...
