Engine Performance problem
2001 Toyota Rav4 4 cyl Two Wheel Drive Automatic 160000 miles

one morning I started my car and it was running on 3 cylinders- rough idle, poor acceleration, hesitating when giving gas. I replaced all the plugs and found a fouled plug in #3 but no improvement in power or idle. The check engine light code read misfire on #3 cyl. I have put two bottles of Lucas fuel injector cleaner in two full tanks and no help. Its not running hot and sometimes runs ok at higher speeds. Coil? F injectors? Cat converter? Plug wires? What can I do?
