Hi guys, so lately my jeeps been giving my some trouble. When i start it up the rpms start going from 0-40 consantly and it sounds like my engine is going to turn off. sometimes it does othertimes it doesnt. Also while my rpm's are going all over the place and my engine sounds like its going to shutdown my jeep makes small backfires.anyone had this problem before?
the funny thing is after a while everything is normal and it runs fine.
My 1987 Jeep Wrangler 4.2L 6cyl manual stick shift
