My '82 GL is having some kind of problem with the electronics in its distributor. I can be driving along for 30 mins. sometimes only 15 mins and she'll start misfiring and the tach starts jumping all over the place. Finally she'll just stall. I've narrowed it down to the electronics in the distributor overheating because if I take my distributor cap off and place an icepack (I know it sounds crazy) on the insides for about 30 seconds she'll start right up, and take me about another five miles before she overheats again. I've been told that you can't replace the electronics alone and that I'll have to replace the whole distributor. I've priced them at about $170. Do I have any other options other than a used one of course?
