Check your ignition timing. If it's severely retarded (late) the engine will lack power and, usually, run hot. If you have a valve tap the knock sensor could be picking it up and retarding the ignition timing. If that's not the case a worn timing chain will retard the valve timing and ignition timing. Resetting the ignition timing in this case will not solve the problem. The timing chain and sprockets will have to be replaced. Hope that helps! Jim
