I am finally admitting stuck. I have a 1987 Wrangler with inline 6cyl Jasper engine. I had a bad backfire issue and may have damaged the carburetor (Holley 2brl). The following is the list of what I have replaced:
- New Holley Carburetor (model 7448)
- New fuel pump
- New EGR valve'
- New O2 sensor
- Replaced 2 vacuum hoese and clamps
- Plugs, wires, dist cap, and rotor were replaced a couple of months before carburetor issue
Previous owners had a lot of things added and removed so a lot of open connectors. However, I was able to drive (albeit rough) without cutting off.
Now I can crank the engine and it idles high then slows down and cutsoff. Played a little with the idle only but cannot get it to stop cutting off. I am obviously missing something. Any ideas or even a good vacuum diagram would be very much appreciated.
