I have an 87 4x4 with a 22r. I am running stock carb and manifolds. One day I will be driving it and it runs great and same day or days later it will start running rough and won't idle. I have replaced cap and rotor, plugs and wires, fuel pump and carb. Any help would be appreciated.

 

Never mind I got it fixed. Seems the standard ignition parts cap and rotor I got we're bad. Got the parts store to warranty them and now I am running great again.
