The Dreaded DTC gremlins .Just looking For Input Well i have a scan tool and noticed my car wasnt runnign correctly ever since i acidently ran 116 octane leaded fuel in my car for the Track .I mixed 2 gallons of it with 10 gallon of 93.ANy way Cleaned my 02 sensors with carb cleaner got rid of the miss but now the codes are Showing .The question is Will any of these codes cause a Major Problem , codes are
P1154 Fuel air metering
P1134 Fuel air metering
P0153 02sensor CKT Slow respone bank 1 sensor 1 and bank 2 sens 1
I know i should expect some codes but im just worried one of these may cause something bad to happen to the engine.And anyone have a idea what would cause the Fuel air meterign to show up it never said if was Rich or lean

153 and 1154 are B2S1 codes and 1134 is a B1S1 codes. You probably ruined your O2 sensors with the leaded fuel. Go to www.gearchatter.com for more specifics.

Leaded fuel kills O2 Sensors, PERIOD!!! Don't try to save them, replace them with stock OEM ones. There should be a sticky in every forum.
You can buy unleaded race gas but do you really need it?
Unless you are boosted or running very high compression, there is no need to run "Race Gas".
BTW - B1S1 is "Bank One Sensor One" AKA Drivers side front O2 sensor

Thanks billiums for puting it in simple terms for me.Im just a country boy decent mechanic but not real good at alot of the tech terms lol.Ya i know the leded fuel will destroy my o2s i didnt at the time i was just thinkign i would add a small amount to help the octane rating and clean the car out since i thaught i had got some bad gas before.I belive i will go ahead and get the Bosch 02s that i keep hearing about that suppose to be alittle better than oems .car has 80k on it so i guess it was just time for them to be replaced

I'm a big fan of the stock OEM O2 sensors. I've seen more "Insufficent Switching Codes" from the Corvette and Bosch ones over the stock pieces when used in long tube headers.
There is really nothing "wrong" with them, just sometimes you get that code more than stock O2s.

I've personally downloaded a tune from a car that was done by a sponsor tuner on here, to make sure the car never had the "Insufficent Switching Codes" popping up, they were turned off in the PCM!
So if a O2 did go bad you wouldn't know right away.
I've tuned over a 100 cars now and only like 2 cars got switching codes with stock O2 sensors and about 5-6 cars that had Corvette/Bosch sensors got the codes.
Seems like, bigger the cam, more O2 issues.
