I've had better luck looking in the truck forums from this site and yotatech (have a 92' 22RE 4x4) and then try and apply those troubleshooting tips to my 90' camry. Seems like the people who are really into fixing things tend to be the off-road guys and are much more helpful.
I got the above link from the truck forum off yotatech
Good luck!
