Hey everyone,

I've got a 2008 350z, stock, except for a Stillen CAI / Exhaust. I can't smog it because the catalyst sensor isn't ready, and I am having a really hard time getting the monitor to run. I've had a local shop install a new cat (they did this because the readings from the driver's side rear o2 sensor were all over the place, after the replacement, the reading remained steady). Although I'm sure it's unrelated, I've got a TPMS light on; my front two TPM sensors are dead, but I thought I'd make that info available in case it was related in some stupid way.

I've put several hundred miles on this car, at steady freeway speeds (60-65mph), trying to get the monitor to run and the catalyst sensor to register readyness. No luck. I have no idea what to do, and I've spent a TON of money on repairs.

Anyone have a similar issue, and have some advice about what to do? Please help! I've only got a short time left before I have to park this thing.



Thanks all.

Coop.
