Yeah well they got the numbers down to 61/61 for 15mph and 45/46 for 25mph. So I am barely passing for 15mph and barely failing for 25mph. Also, I have recently done some research on hydrocarbons and catalytic converters and I learned that the chemical compound in a catalytic converter that reacts with hydrocarbons to burn them off can be damaged and coated, preventing them from working to their full capacity by using leaded fuel. Well about 30k back I bought a 5 gal drum of 112 from a race fuel station. I put a gallon in per fill up over a 5 week period. I believe I may have damaged my catalytic converter. Shhhhhhhhhhhhhhh...oh well, so maybe this is it? What more is there to do when you really cannot find anything wrong?
