Hi guys-

Been a while since i've been on here. Haven't had a problem in quite a while. Looking for some info here, I failed emissions here in TN due to "cat not ready" and "evap not ready". Drove around with my own OBD II tester and found that the "o2 not ready" came on and the "evap ready" fixed itself. Seems intermittent with the evap system. The Ho2 showed as ready though.

On a cold startup the o2 sensor registers as ready. Then not once the car heats up.

Also, I've been throwing a P0420 code for some time. I cleared the code and headed to the inspection place. But since then I cannot get my catalytic converter to register as ready. Read all over here about the failed cat converters.

SO:
Any advice on the intermittent "evap not ready" code?

Since I am throwing an o2 not ready I/M do you think that is contributing to the "cat not ready" I/M?

Looking into getting a new catalytic converter next week. Just want to weigh my options in the meantime with a solid forum like this one!

Jeff - check prices on aftermarket converters...the dealer ones will be spendy.

Well I managed to finally pass inspection today. After much reading through the forums I looked up the attached chart on the "Driving Cycle". This was a huge help because all I was doing was getting on the interstate and going fast to heat up the exhaust system. Apparently all I needed to do was drive for 10 minutes and keep it under 60mph. I was doing 70-80 on the interstate (that's the minimum in memphis :) )

Went to the inspection station that was further away (the first one was 2 miles and maybe 4 minutes to get to) and passed!!!

The quotes I got varied a lot. Called 3 dealers and got quotes from 1,040 to 1,500. Even called some local shops and the part alone from them was 900! Autozone sells the generic oe replacement for 400 or so.

Anyway, happy to get "the man" off my back for another year. I am going to have to get the o2 / cat converter issue worked out in the long run. Don't want it to deteriorate and blow back into the engine.

I would say the most important thing about the purchase of the catalytic converter in a state the does testing is you will most likely need to get the oem part. I dont think most aftermarket cats are carb certified. Carb certified is what your looking for in testing states. I've heared they will give shops a hefty fine if they install non-carb certified cats on customers cars.

Glad you mentioned The Driving Cycle. I put it in italics to catch the attention of future readers.

I first ran into this with a BMW, but it's common to many cars. After some procedures related to the emissions system, the car must be driven through "the driving cycle" to reset the OBDII systems.

Here's a link to one description of that cycle: How to Perform a Basic Drive Cycle
