I have an 87' 4runner 22RE. I tried to get my annual inspection today and failed only on the low speed test. High speed past without a problem. I have a brand new catalytic converter and was able to pass last year. I haven't noticed any changes in how the engine runs. It has started idling higher recently though. I'm not sure where to look. It seems like the cat. is ok I hope and that my truck is just running rich at idle.

How much higher is it idling? I am assuming it failed for HCs? Did you try jumping out the connector to see if there are any codes?

Some 411 about what actually failed would be nice.

For real. Did it fail HC or CO? It could have failed because its idling too high, outside the range of "idle" for the tester machine.
