PUR NRG

Installed Scott's plugs for the leading positions. Unfortunately the shims provided for trailing are slightly oversize. It's a bummer but trailing were already #9s so it wasn't that bad. Unfortunately I still have to retard timing in order to avoid pinging--and even with a couple degrees pulled I still get occassional ping when stepping on the gas.

Prior to installing the plugs I had the following CELs:
P0300 Random/multiple cylinder misfire detected
P0410 Secondary air injection system malfunction
P2021 Intake manifold runner position sensor/switch circuit low bank 2 a)
P2096 Post catalyst fuel trim system too lean bank 1

After installing the plugs I had the following CELs:
P0172 System too rich (bank 1)
P0003 Fuel volume regular control circuit low

We'll see if any more CELs crop up now that the plugs are in.

P0003 isn't a valid CEL for the RX8... make sure you have the car off and the ignition turned to "ON" when reading the codes - not sure why you have to do it, but random codes seem to crop up every once in a while if you read the codes with the car running

It may not be valid but I got it again, this time with engine off as you suggested.

PUR, does your shop manual list the P0003 code and how to troubleshoot it?

thats weird... maybe talk to Dan and make sure you have the latest Canscan software?
