my 2000 malibu is making a vroom vroom noise when started and it bounces
the car a little sending the rpms to the 3000 ( 3) mark. We had the gas
filter and stuff cleaned out and it still makes the noise and movement.
Makes it hard to back out. Uses a lot of gas in one day. Half a tank and
have to fillup again. Any help?

Sounds like your fuel pressure regulator is bad....When it starts to
leak it will dmp too much gas and give you a speratic idle like you
state..
