Anybody know anything about 90’s vacuum controlled EGR systems? I’ve got one of those goofy little Japanese import trucks, and finding info about how it’s supposed to work is a nightmare.
There’s a pretty good vacuum leak out of the top of the vacuum amplifier/signal doodad. Kinda UFO shaped deal between the vacuum advance, intake manifold and the canister.
Any ideas on diagnosis, or ways I can figure out what’s doing what would be helpful.
Jdmfsm.info and charm.li may have some factory manuals you can use for diagnosis. If it’s true JDM though there may not be manuals you can read.
Thanks for the links. I’m pretty used to Google translating these things at this point. It’s funny every time I find a manual for this Japanese rig it’s in Russian.
