Re: failing smog computor says cataletyc not ready it...
Check the oil level, to much can ruin catalytic converter. Check O2 sensors with scanner, make sure they are work accurately. Check air box while car running, apply aceteline gas with no flame, recheck scanner for O2 sensors flucuatation. Compare all sensors for flucuation of 1mv to 9mv. If sensors flucuate they are good, if no flucuation sensors need to be changed. recommend to change cat with bad sensors. Before changing cat check for bad pressure.

Because of lack of information (data) about your inspection, it is hard to tell where the failure is.
For more information about changing catalytic converter. The price can be 10 times different.
The highest quota I got was over $1400 (the golden smog station), the lowest was below $200 (found by state division where I asked for compensation due to old car -- since I cannot go there directly, I paid $325 fro an agent to do it). Dealer was asking for $700.
After changed a home genie catalytic converter, which worked better then the original manufactured till car is dead in another 10 years, I brought it back to the golden smog station for free re-test. The technician did not believe that is a new, and inspected to verify that is true.
This homegenie catalytic converter passed a number of smog tests till car is dead after another 10 years.
BTW, the original manufactured catalytic converter failed on the very first smog check at year 6 or 7 after can was bought, so it is possible you had a failure catalytic converter, but inspection result may tell.
Well you'll need to find out what is making it emit the high levels. Is the check engine light on? You may need to replace the catalytic converter. Also, verify that all the smog related items on the motor are connected and working.
did you fail a smog test? if you did... i always pass smog because i always have a new catalytic converter installed .if i was a little over the test, this usually gets me down a little lower and that's passing!
I have a 98 Montero Sport and have yet to fail a test. I have changed a CAT Converter for 200 and some O2 sensors for 50 per since i had the car. you can get a aftermarket universal O2 sensor at a good price as for the CAT Converter ya they are expensive I just knew the guy. As for the dash light disconect your battery it will reset it
We had to have the calatic converter replaced. We did this after doing an oil change, air filter change, and new spark plugs and still hadn't passed smog. After changing the calatic converter it passed smog with scores of 25.
