Hey everyone I'm new in this forum. Just picked up a 1991 T4R 3L 4x4 auto. I had an intermittent check engine light so I decided to try to pull the codes from it and see whats up with it. I got code 12 and code 22. Anyone know what could cause these and what they are? Also with the O/D button on I get flashes from the O/D off light and from what I'm reading here that could be cause by a speedo cable thats going bad? I would appreciate any help. Thanks
