Hello everyone,
I just bought my 94 and it had a miss and changed the plugs. I found one that was fouled and solved the miss but I'm getting 12 mpg city and under 14 mpg highway. Car seems to run fine to me but my first vette so I'm not sure, It only has 39k but previous owner didn't drive it much. He told me he started it everyday and drove it once a week. I believe it started and let it run for 10 minutes and when he drove on his property. Probably just idle when he was driving. Any ideas of what it could be? I appreciate any help don't want to start replacing things that aren't necessary.
You don't mention it so will assume there are no codes. When the 02 sensor on my 95 was going bad the milage got horrible, but it did throw a code pointing at the sensor. Are the mpg numbers you note by hand calculations or what your display states?
