Mpg Hey guys,
Just replaced my O2's on my 93' fire birdy. Being a 93' - it has no MAF.
Anyways, i replaced them because it seemed to be running a bit on the rich side - and my gas milage was TERRIBLE. Now that i've replaced them, I've been averaging about 11MPG city. Is this normal? should i get more? (yes, i have a heavy foot. But why drive this car if you don't?)

Thats WAY off for a 6 speed... I'm running through a 4spd auto with 3.73's and 3600 stall (terrible for gas mileage) and I'm still managing 15 in the city with a HEAVY foot

Yea that's lower than average. Mines averaged 24 mpg even tho I was on the freeway most of the time but my **** still gets way better than 11 mpg in the city too. You need to check your tune-up items(opti, plugs, wires, fuel pump, etc) because I think you're gas mileage is lower than average.

my car used to be auto so i think my gears in the back are not the greatest but my mpg on the highway (i kid you not) 30+ in the city is about 19. im sure my 1/4 mile time will improve a lot once i get my 4.10 in there!!
