1996 Sable 3.0l

No cats, resinator, or mufflers.

my check engine light is on.
I get pretty bad gas mileage.

would those MIL illiminators give me better gas mileage and stop the light.. or just fix the light.

also, would it have better response, i know the sensors make the fuel ratio change because it thinks the cats arent working right so it dumps more fuel... am i right or wrong..

Sounds great by the way....

The H02S sensors downstream of the cats only check to make sure that the cats are functioning properly. They do not control the A/F ratio; that is what the upstream H02S sensors do. The MIL eliminators will simulate a properly functioning sensor, and eliminate the MIL. It will not affect the gas mileage or throttle response.

A friend of mine has them on his mustang and they don't work right... I dunno if it was specific to the brand he bought... but they just don't work for him. :blink:

They only eliminate the MIL light. Most good chip programs do this also.
