I have a 2003 Chevy Tracker, with a Suzuki 4 cylinder, 2.0L engine. Up
until the last couple of months, I would easily get 600 KMs to a tank
of fuel, but now only get 300 KMs to a tank of fuel. My mileage has
dropped by half.
I have replaced my spark plugs, changed the fuel filtre, replaced air
filtre. Doing this made no difference what so ever in improving or
restoring my fuel mileage.
After some thought, I have come to the conclusion that my timing belt
may need replacing and reset. I have not started on this process yet,
but am not sure if I have a timing chain or timing belt.
I have notived that when the engine is idling, the RPMs are only at
about 700RPM, where I think it normally would be around 1,100. So this
is making me think the timing chain or belt may be the issue.
Has anyone else experienced a problem similiar to this? Does this
engine has a timing chain, or timing belt?
I look forward to your experiences and thought on this.
