I just wanted to tap some of the smart people here for some advice.
My '02 Malibu with the 3.1 engine and 54,000 miles was recently worked on.
I had the Intake manifold gasket as well as the Head gasket changed Along
with that the mechanic insisted he change the Spark Plugs and the Ignition
Wires. SO far so good. THe Ebgine feels good. but the gas Mileage is barely
OK. Im getting about 200 or less miles per Tank. Thats about 12 gallons when
the Guage Light comes on and I fill up.
Question? Shouldn't the Mileage be better for such a small car. I do lots of
driving to Manhattan from the outter boroughs and theres aobut 50% highway
driving. Lately Ive had the A/C on and theres much less pep in the Pedal.
Is there something that goes wrong on these cars that would mess up the
engines performance or gas mileage?
Is there something I can check ( Timing? Dwell? Vacuum pressure, etc)?
Any ideas are welcome.
Thanks In advance
