Gas mileage question
Earlier this week I accidentally killed my battery. Before it happened my average mileage was right around 17.5 mpg. Now it is down to 12.2. Is it normal for the car to do this after loosing the bat, and will it correct its self. My baby is a 1995 btw. Thanks in advance for any help.

I'm surprised your only getting 17.5 mpg. My 1995 with the performance rear and auto trans gets around 20 mpg. I had a 1990 with the standard rear, auto and that car averaged around 22 mpg.

22 mpg is my average (mostly highway) and that's with bad injectors and a code 32 for the EGR, I hope to fix both this winter.

So if I am seeing low 17s and have an auto with 3.07 gears. What should I be looking for to correct this problem? I noticed since I changed the coolant my mpg has gone down. Before I was in the low 22 for an average.

If your driving the car to charge the battery, your overloading the alternator.
This can/will cause two undesirable results.
-Burn up the alternator due to overloading
-Burn up fuel while overloading the alternator
Always fully charge after killing the battery.

Fuel Mileage
I'm getting 17.5 around town.
1984. Engine stock original with 164,000 +/- miles on it.
I've owned it for the last 15 years and it's been very 'trouble free'.
Now that I've said that, the fuel pump or water pump or SOMETHING that pushes, pulls or rotates HAS to go out.
Oh well, it's a very simple fuel injection system that is easy to work on.
The rest of the '84 is easy to fix as well.
BTW it has the Z51 option. LOVE that quick steering ratio and the flat cornering. She really hooks you up with the road and drives like a go-kart.
How does my C6 get 22.5 around town with TWICE the HP?

Charging a dead batt is hell on the diode pack and windings (to less extent), especially in hot weather. Nothing like also replacing the pack or the entire alt. to add insult to injury!
