Why does an engine run roughly?
if it's runninng rough my guess could be spark plugs are fouled up. if not then next check the spark plug wires then the distributor.
Not likely. A broken Camshaft would cause a car to not run at all, unless maybe it had 2 camshafts, then it might barely run and run loudly then quit. The most common reason for an engine to run roughly is neglect; too little maintenance or tune-ups, broken hoses, wires or sensors, dirty air filter or dirty fuel. .. lets not forget .. an engine jumping time.. if it will still run it would run…
NO! Don't attempt it. Don't run diesel in your gas engine and don't run gas in your diesel engine! It will cause your engine to run improperly with loss of power and lots of white or blue smoke. It will clog your engine and if you run it with the wrong fuel too long, will result in complete engine failure.
