My sons 84 4x4 GL hatch recently started running rough. I changed the rotor and dist cap and it ran like a charm for a little while then got bad again. I then changed the spark plugs, wires and coil, it ran fine for a while then started again. I have come to the conclusion that it is not in fact related to the ignition as it ran fine on the way to the grocery store just now and terrible on the way back! It makes no difference if it is hot or cold. It idles very smoothly however lacks torque when taking off and cuts out when running. The strange thing is that it stops and starts without warning or pattern, one minute it runs great the next its hard to get through a stoplight. Any one have any ideas? Thanks for your time, Tom
