Default gas mileage estimate

how many mpg should i be getting i have a 96 ss lt1 with longtubes ory and 3" exhaust with no cat. i reset my trip every time i fill up and i'm only getting 12.5 mpg average my exhaust smells like i'm trying to **** off the ozone layer. i have a right bank 02 sensor code i replaced the sensor but the scanmaster is still throwing a P0154(02 sensor ckt no activity bank 2 sensor 1) the mechanic who put in my new timing chain and oil pan gasket said that because i have no catalytic converter the air was passing the 02 sensor faster than it could read. i also have a P1441(manufacturer control auxillary emission controls) what causes a P1441. I have a Simulator in the 02 ckt for the cat.

Check the wireing. The no activivty is from there being no connection not a faulty or bad reading. No reading at all on that side would for sure cause it to be rich. As for the P1441 I have never had to deal with it.

Agreed, your mechanic is an idiot. Don't take your car to him anymore.

These people often have kooky misconceptions about anything electronic in these motors.
