1988 Toyota Dolphin

Hey guys I have spent the day doing research on why my Automatic 22RE motor is shaking profusely when idling and then when I put it in Drive or Reverse, the motor bogs and most of the time stalls. I have read a lot of threads about bogging issues on acceleration and such but not on an automatic just shifting into gear. I have noticed, even in park, that if I rev it high and then pull my foot off the petal immediately, it bogs and sometimes stalls. I would say it is the worst when in Reverse. It stalls regularly in reverse when you let off the accelerator. I have adjusted the idle to the point where the screw is just about to fall out and it seems to help a little when put in Drive. I know it might be a vacuum line leak and I am going to try to check into that but if you have had this problem and fixed it PLEASE HELP!! I live in this motorhome full time and travel so an unhealthy motor means an unhealthy home....

Thank you,
Jordan
