Missing at idle
Hi everyone. I recently bought a YJ with a weber carb. It has been nuttered. It had an exhaust leak so I pulled the manifolds and replaced the cracked exhaust manifold. I also pulled the valve cover to clean it and replace the valve cover gasket.
The problem I am having is that at idle the motor misses and dies. When revving it has no issues whatsoever. Here is the list of what I have done so far to try and fix it. I am at my wits end and hope you all can help me.
1. New distributor cap, rotor, plugs, and wires.
2. Checked all post nutter vacuum lines based on threads I have searched on these forums.
3. I have some extra electrical sitting in the engine compartment that I haven't had a chance to get to. It is all pre-nutter wiring.
4. Went through all 6 plugs and disconnected them all 1 by 1 and the missing was worse on each of them. No single plug seems to be the problem. Plus when i rev the motor it does not miss at all. It does when I revved with each of the spark plugs disconnected.
Could this be a problem with the EGR valve? Timing? I have been searching the forums for hours. Maybe I'm not searching for the right thing but I'm about to tear my hair out.
