From what I understand this is a lean code I have drained the aisin vaporizer and inspected the filters they where dirty. I checked the trim injector and is does no look clogged. Ran the unit with the filters removed and have had no change. The truck runs ok when given gas. When throttle is released unit idles up and down. The code clears itself when you raise the idle for about 20 seconds. Any help is appreciated.
