I changed the wires and plugs rotor and distributor cap on this vehicle I am trying to revive. It has been sitting for a few years. It runs fine on the open road but when it is first started it idles unevenly. If sitting at a light it may die. Putting it in park helps but I would like to get this right. Is there an adjustment for the idle speed?
