22re running rich
So I just picked up an 86 4runner with the 22re. Drove it 3 hrs home. Runs pretty solid, idles well, but is extremely rich. The entire cab reeks of fumes after getting up in 2nd and 3rd gear. It was so bad after driving home my eyes were hurting lol. Obviously failed smog because of high hc levels. Just wondering what I should be troubleshooting first here on the 22re. There is no check engine light on and couldn't get any codes to be thrown. Dont know what was wrong there but that's for another day I suppose. Any tips would be very helpful. Thanks!

Did the PO change or upgrade the injectors?
I tried some bigger upgraded injectors years ago and eye burnage was involved, either way it shouldn’t be in the cab, any exhaust leaks?

You probably have an exhaust leak as well as cabin sealing issues.
Inspect..
Exhaust plumbing.
Evap system.
Firewall, and rear cabin seals.
Then figure out why (if needed) it isn't entering closed loop mode (ECU controls AFR).
At a minimum you're probably going to find issues with the oxygen sensor, like it's not reading the exhaust stream due to leaks or grunge. Your tail pipe doesn't extend outside the under side of the body. The rear window seals are shot.

I would pull the thermostat and see if it is stuck open. New thermostats are easy if needed. Always buy a toyota one.
A stuck open thermostat will prevent the engine from warming up properly. They open and close as needed based on radiator coolant temp to keep you engine at the right temp. Often times people have one fail and don't know better and install a "fail safe" one in there. DO NOT put one of those in. They seem to fail, permanently open, every time in Toyota's.
