I have a long term engine stutter or miss at a certain throttle position, just above cruise speed. It's been going on for 30k miles with no change. Engine computer reports #3 cylinder misfire. Otherwise it runs smooth and gets good fuel economy.

Spark plugs, wires, rotor and cap have all been replaced. Doesn't seem like it should be the injector, since it performs well in all other throttle positions and the miss is erratic when it occurs, sometimes worse. Can the throttle position sensor cause this type of malfunction? Or? Carbon in air horn? Just wondering if anyone else has had this type of malfunction and resolved it....
