Today my truck started skipping. It was running fine when I stopped at a stop light, then when I gave it gas to pull away from stop it was skipping, just like that, no warning. I was only 4 miles from work so I kept going. When I was about 1/4 mile from work at a stop light, smoke started coming out from under the hood
(electrical smoke by the smell). So I got to work ,were I had a fire extinguisher, popped the hood and what ever was burning up had already stopped.
I did find #4 coil split and melted plastic coming out of it. So I replaced the coil and truck still skips. Replaced the 8 spark plugs under the coil packs (that is all they had at Napa) I will do other 8 when I get them. Truck still skips.
I found #'s 4,6,3 not firing according to my timing light. I need to check these coils for neg. and pos. to see if they are getting signal from ECM.
Anyone have any idea what may have happened, or better yet what I should look for ? Is it possible the coil shorted and burned up ECM ?
