p0420 cel
I just bought my my 04 last week with less than 1000 miles on it. After launching the car for the 1st time the cel came on. I just purchased an ACTRON scan tool and cleared the codes .I had a p0420 code and a p0420 code pending. Should I be worried about it? I dont want the car reflashed and I dont want to bring the car to the dealer. I guess I'll just wait to see if the cel comes on again. How do I know what version software my ecu has and if the car has already been reflashed?

p0420 is a Catalyst Efficiency Below Threshold and pending codes are also referred to as “continuous monitor” and “maturing codes”. An intermittent fault will cause the computer to store a pending code in memory. If the fault does not recur within 40 warm-up cycles, the code will be cleared from memory. If the fault recurs a specific number of times, the code will then mature into a diagnostic trouble code (DTC) and the MIL or “check engine” light will turn on.

You might ask him to check the catalytic convertor, but I'll bet that code sends him right to it.
Ask them not to flood your car moving it around their lot. See this post: https://www.rx8club.com/showpost.php...7&postcount=23 for a helpful sign to print. Hang one over the stereo and one on the inside of the driver's door.
