Does it pass emissions now?
What did it fail on? hydrocarbons, nox, or co? I am willing to bet the two problems are related. The other sensor I would test it the tps. What is your fuel pressure at? Ray.

Yes, it has passed emissions twice now. The original problem was a bad O2 sensor, and the replacement O2 sensor was bad as well. Finally had a mechanic who specializes in Toyota's look at it, and he found that problem.
I don't know what the fuel pressure reads. I have a gauge, but it is for GMs and Ford's with screw-in schreader valves. The guide I have says to make an adapter by drilling a bolt. Does anyone have a better adapter/solution? |

There are adapters to fit toyota's but it might be too expensive just to test this out.
Does it feel like one cylinder is missing, or all of them? I would check the plugs, and wires, timing, and test the tps. Otherwise I really don't know.
