Hi, I still drive the '88 Wrangler I bought in Oct '87. She has 171,000 miles. Recently I had a rebuilt motor,transmission, etc… installed. I had the existing carb rebuilt. This summer , while driving at any speed, the tach would drop to zero and the whole car would lurch. Sometimes so violently my seatbelt would lock up. After a couple miles of lurching it would backfire several times. (these symptoms have become known as belching, vomiting and farting) This is very scary. Several different mechanics have posited several different possible causes.
Here’s the really bizare issue - now that the weather is cold, the issue has substantially (not completely) diminished. On a warm day in the 50’s it will act up again. I live in Watkins Glen, NY. Yes, I’m a (Indy Car) racing fan.
What’s wrong with my baby? What can I do?
