i have a 99 grand pix with the 3.1


ok got a couple problems:

First one is i changed fuel filter now car doesnt like to start after its been sitting like 10 min. before i changed it would fire up real quick.

second prob when heater switch is on def. and i turn on fan i hear ac unit kick on but not when its off def.

thirdly drivers window seems to get stuck on the backside of window frame when i roll it up. not sure how to line that up

and can anyone tell me roughly what my mpg should be?

Thanks!
