July 6, 201411 yr Hey all, I just installed an EJ22EAWBPL engine, taken from a 96 outback legacy (manual), into a different 96 outback legacy (automatic) that previously had an EJ25DAABJL. When I start it up, the engine constantly revs up to 3K rpm, then drops a little, then revs back up. It will do this until it is shut off. I can't figure out for the life of me why it's doing this. Any ideas?
July 6, 201411 yr double check ALL of the vac hoses. you left something open, disconnected. you may end up with a trouble code due to no EGR.

Same thought, a disconnected vacuum hose somewhere causes what you describe. You may have a vacuum hose that is partially cut open that could be the culprit. Also agreed, the 5 speed engine prolly does not have an EGR, where as the automatic does have an EGR. That prolly will trigger a check engine light. There are ways to fix this, if it presents itself to you.
