I was looking at some amps and such yesterday at a store. On my way out of the lot I had to sit for about a minute waiting for my chance to get out when I smelled an electrical burning smell and the engine began to mis. It was in about 3 second intervals. I searched for idiot lights....none. I took off and went about 2 miles and stopped again and really felt and listened...it was gone, both the smell and the mis.
I returned home and let her sit idling while I raised the hood and smelled and felt the engine. No smell, no mis.
