Default FJ60 emissions help

Hey, ya'll, it's Shorty. I hope that you guy(ettes) are doing well. I have a question for the LC experts.

I recently sold my 1984 FJ60 to a young lady in New Mexico. She has not been able to get it tagged because it failed 3 emissions tests. That surprised me because it sailed through testing here in Denver last year.

Anyway, she sent me a pic of the failed test report. Here are the numbers:

High Speed RPM=2381

Reading Limit
HC 153 220
CO 4.77 1.20 <-- Failed
CO2 11.6
O2 0.07

Low Speed RPM=922

Reading Limit
HC 419 220 <-- Failed
CO 0.01 1.20
CO2 11.9
O2 3.61

She already changed spark plugs.

Does anyone have any ideas what might cause the failure?

Thanks a bunch!
Shorty (A.K.A. Mark)

My experience with FJ60s and emissions issues usually came down to a weak cat and weak air pump. If the air pump isn't putting enough oxygen into the cat, it doesn't work right. If the cat is weak then it really needs a strong supply of O2 to react out the nasties.

I don't think that it has a cat. I will tell the woman to check if it does and pass on the info about the air pump.

Thanks!
Mark

All FJ60s had cats (in the US) and if it passed emissions here then they checked for it.

I had it all those years and don't remember if it had a cat when I got it. Maybe the PO removed it. Must be getting old. Wait. What was I typing about?

Thanks for the help.

No problem, there is an emissions manual she can download that can check the air injection system. If that is working, and the air pump is working with a cat, that will narrow down the issues.
