The engine has suddenly started running very rough. On the road it will run very rough with little power and then all of a sudden will run normal then all of a sudden will go back to running rough. Checked plugs, plug wires, fuel & fuel filter. All check out OK. If the throttle position sensor (TPS) is unplugged it seems to run much better although not normal. Replace TPS, any suggestions?
