1997 Toyota 4Runner SR5 3.4L Poor Idle Quality, MIL Lamp on
This 4 Runner has been a real stumper. The engine light comes on at idle during the transition from cold to warm. Just before it gets to normal temp the idle will get a little rough and the light will come on. It was giving me codes 300, 301, 302, 303 and 304....
