    I just did a smoke test. The only smoke I see is coming from the air filter box because it won’t close all the way. Either it’s shit aftermarket part or something else. Could that be causing the code to pop up?

    Your code would have me looking at your o2 sensor.

    It's less Tacoma and more mod
    Also the way you tested it neglects to test the brake booster and it's check valve. Maybe use that port on the front of the intake manifold to run your test and leave the brake booster hooked up

    Ok, I probably should have looked at that as well.
