What are common problems for too much fuel being used?
I work about 8 miles from work but is taking about 1/4 tank of gas to get there. Just replaced the fuel pressure regulator, with a kit, but still consuming too much gas

    Pull the codes on your model year it will send them to the check engine light on the instrument panel ,some of chain parts stores will give you the jumper , They will most liklely show you where to plug it in . Hook up jumper and turn the car s key on ,off ,on to the run position (do not engage the starter)
    Codes are sent to the light as blinks
    Example code 22 would be 2 long blinks and 2 quick blinks
    code 34 would be 3 long blinks and 4 quick blinks
    It sends codes twice back to back and then procedes to the next
    Have you given it a complete tune up ,plugs,wires,distribor cap,rotor button,pvc valve
    Also check for vacuum leaks
