CEL light troubleshooting
ok guys here's the issue:
I have a 2004 automatic rx8 with 91000 km. I had a bad coil last year so I replaced the coils/wires/plugs at 87000km and had an oil/filter change at 90000km before putting the car in storage for the winter.
I started the car about a week ago after having it away with the battery out. It took about 15 minutes and a couple rough idle stalls before it started running smooth, I'm guessing it might have been burning rich??
I drove if for a day with no issues, then added some marvel mystery oil to the fuel as a fuel treatment. About an hour after doing this it flashed a solid CEL.
When I'm using the paddle shifters in second gear and redline, sometimes the CEL will blink 3 or 4 times then go back to solid. Also the red led redline light that usually blinks isn't coming on anymore.
Any ideas folks? I doubt it's the plugs coils or wires they're OEM with 4000km on them and there's no rough idle or power loss like I experienced when I burned out a coil last year so I highly doubt it's a misfire either.

Get the codes read.. Likely misfires. Its possible your fuel trims are all out of whack since your battery was pulled. Would take a couple drive cycles to settle down.
I'd do the following:
Get the codes read.
Reset the ESS (20 brake stomps with key on within 5 seconds of turning on key - engine NOT running)
Drive for a couple days.
If the CEL blinks again be prepared for further diagnosis. Possibly wires, plugs, and yes even coils.

Assuming you have the latest flash (all of us should at this point) your oil pressure gauge will sweep.
You've got to be fairly quick with the stomping too. Don't be leisurely about it.
Get those codes pulled. I'm really curious if its just misfires or if you threw a lean code too on account of the MMO.
Guess you should also check your catalytic converter. It should not be glowing....
