Thank you for your response Zackman. Actually, my mechanic has done the following. Replaced the wires, plugs, injector, and tested compression. The engine light stays on and the engine idle is rough, although plenty of power with smooth acceleration. I am assuming both the engine light and rough idle are related, which may not be the case. I am also assuming P0305 is the trouble code as he indicated #5 was the issue. The diagnostic steps above are out of my competence since I lack the equipment although I was once a fair wrench. One thing I did notice is that the idle smoothed and the light went out when I filled the tank full with fuel. This happened two times. The rough idle and light returned when the fuel indicator reached the half way mark. I am thinking of having the fuel filter changed. My mechanic is thinking an intake manifold check. Again, thank you for your suggestions.
