Hi there. A couple things come to mind. It could be starving for fuel. It could be something as simple as the fuel tank not venting properly, and you could verify this by removing the fuel filler cap when it starts to run poorly. If you hear a whooshing noise as you remove the cap, the tank is no longer venting properly,and the engine ends up starving for fuel. Another possibility is the pick up coil in the distributor gets warm and delivers an intermittent signal to the ignition module. That would cause the symptoms you have described. When it acts up, pull over, remove the air cleaner, and move the throttle linkage. You should see some fuel squirting into the carb. Engine off for this one. Hope that gives you some ideas. Canuck
Hi there - any progress on the Jeep?
