88 yj running rough
I have an 88 yj with 4.2 and Weber 32/36 carb. It has the nutter bypass. Under load it is missing and has got progressively worse in the past few weeks. It used to happen at higher rpms. Now it does it at any rpm. I put née cap and rotor plugs and wires. Along with a new fuel filter. It has a new coil also. Could it be the original exhaust plugged up or off time? Any help appreciated.
