Ford states that 02's should be within 17" from the exhaust port for proper operation, reason your gauge read rich all the time with stock exhaust is FORD programs the EEC rich for safety reasons (extended WOT).

My A/F gauge was my digital voltmeter hooked to 1 of the 02 sensors, the reason it bounces all over when just driving around is because the computer is constantly trying to achieve the Stoichometric A/F ratio of 14.7:1, which is perfect, you will only get a "constant" reading when at W.O.T.

Hope this helps.....Good Luck! Camaro's suck!
