Chevrolet: 1998 mailbu 4cyl 2.4L

hi i have a few question about my 1998 chev malibu 4cyl 2.4L it has
230,000kms i just bought it a month ago

1. what would normal gas mileage be for this car? i get about 350-370kms
for a full tank. thats highway/city driving. Is this normal milage for a
malibu with this many kms?

2. the car has a bad shake in the steering wheel when i get up past
130kms/hr and start braking, then if i speed up more the shake will
slowly go away

i googled these questions but i never got no real good answers so i was
hoping someone here could help

thanks

chris

Might be time for a tune-up. My '98 with 290,000 kms, 3.1L V6 gets 34-35
MPG hwy, don't know about city. I recommend spark plugs, plug wires, PCV
valve, air filter and with that many miles, you should check the fuel filter
too. Mine was nearly clogged when I changed it 10,000 kms ago.

The shaking in the front end is probably from bad rotors. These cars are
notorious for bad front brakes. Check the sliders on the calipers while you
have the brakes apart, they may need to be cleaned and regreased.

Good luck,
