I was wondering what anyone has done to solve the P0312 code from coming up. I have a '97 TBird with a 4.6L with just 34K miles. The book says this code is too lean, Bank 1.

Thanks, Phil

That is an odd code, since 0301->0312 are misfires for a specific cylinder, and that car probably doesn't have a V12 in it. Was it a p04xx?

Funny you said to do that because I did those things earlier this morning. So far, the light is still out. I sure like that MAF spray. When I do it, I remove the two small screws on the plate and spray it from both directions. A little blue locktight and I reinstall the plate using my little vice grips. I see the OEM screws are a special torx screw with a small peg in the middle to prevent a standard torx from working.
