i cleared the codes and let the car warm up before driving. After a 20 minute/ 22 mile drive, the 0306 code did not reappear, so I am assuming this was an isolated incident and was the cause of the flashing CEL.

but i did get PENDING codes 1123 1125 1128 1130. no CEL, but four codes showing both rich & lean issues. i'm stumped (as usual). Is it a risk to drive with these codes ? Or was it just the 0306 that was risky?

Also, I'm wondering if the cause might be A) 87 octane gas ? B) the car takes forever to warm up because of bad thermostat?

a pro repair maual and a good scan tool are needed so you can follow the diagnostic repair tree. a code reader is sometimes a teaser. a no cel means you can drive it but it seems you have other issues....gas,stat,soft codes and other surprises

Hello.
I have read several posts about 1123 and 1125. These are the codes I have. I am not finding a definitive answer if it is made or co2 sensor or the proper way to test.

Any ideas would be greatly appreciated.

Take care


I have taken out the market and cleaned, erased codes and they came back.
