Hate to be the guy that registers and posts what I am hoping is a question with an easy/ known solution. Been lurking here off and on as I needed to find information, I had a lx470 that I sold this last year and recently purchased a 92 fj-80 with some issues. Looking to fix the issues and turn it into a DD, expo and mild wheeler as I already have a built 4runner.
The first issue that I am trying to track down is why I am having a run-ability issue. I first noticed the problem after driving on the highway for 5 miles and then coming to a complete stop. RPM’s dropped from 800 to 200 and almost stalled. It has since started doing it more frequently, not even at a complete stop in park by just revving the engine. Has not actually died yet and requires no additional throttle from me to keep it from stalling.
I did jump the CEL and there are not any codes coming back from the ECU and I also checked out the Fuel pressure pulsation dampener to see if it was missing the set screw and it was still there and tight.
Please see the videos to get an idea of what the RPM’s are doing. Is this a common problem with the 3fe? Been searching and found nothing that has helped.

So far, I like the rig and would like to bring it back to 100% as the motor itself seems pretty solid and the whole rig only has 139k on the clock.
Thanks, Josh.
