Cj backfires after shutoff
My heap, I mean CJ, does a funny thing when you drive it for a while and it gets good and hot. Once you shut they key off, the engine shut right off, no run-on, and then 10 seconds later, it backfires. Sometimes the backfire waits 30-40 seconds so I think I'm clear and get out, only to have it sneak one out while I'm standing in the middle of a crowded parking lot. (Can you say duck and run so no one sees you)
It really only does it when its very hot outside, or I've been driving a while.
