COIL "Breakin' Down"???
Have 88' BII, 2.9ltr-5spd. Have new Distributor Cap, rotor, new plugs and wires. Ignition Module is bout 2 years old as well as the battery. Coil...AND Alternator around 4 years. Anyways, after i get up to operating temperature(Round 190*)the thing develops a "miss". AND, it doesn't do it all the time it's intermittent. Depends alot on the outside temperature. Could it be the coil "breaking down" or maybe the alternator cutting on and off? Thanks! <!-- / message --><!-- BEGIN TEMPLATE: ad_showthread_firstpost_sig --><!-- END TEMPLATE: ad_showthread_firstpost_sig -->

alternator would not affect the ignition system in your case. check the codes first. about the coil. You say it's intermittent - if it seems to misfire at high humidity check for "loose" sparks under the hood. They are clearly seen at night w/o any light source around. If any, clean the coil body, the wires etc. this could help for a while.

If we are talking about misfire due to humidity - it does it all the time, but gives big problems in rainy weather. What I was trying to say - do not blame the alternator. A car can run even w/o it for some time, as long as the battery supplies power to ignition system.
