Anyone having trouble with Ethanol blend fuel? The county I live in mandates fuel with 10% Ethanol content (for lower emissions they claim 
). Whenever I fill up locally, I get an SES light and P0420, and P0430 codes. So I usually fill up near where I work (different county, no Ethanol in fuel) and I get no codes. Well, now that county also requires the Alky-blend, so I have to burn the 10% Ethanol fuel. Is anyone else having this problem? I plan to install O2 sims to solve the SES light issue, but would like to hear other opinions. Thanks.

The F-Bodies were not designed for it and your car will run crappy. If it is E85 or similiar there is programming that needs to be done and the internals need to be protected a bit with a synthetic oil.
There is another called E85 which is 85% Ethanol and very nice but again GM did not offer it with the F-Bodies.
