Losing MPG's

Asked by Walter Mar 28, 2009 at 02:29 PM about the 1997 Pontiac Grand Am

Question type: Maintenance & Repair

1997 Pontiac Grand Am GT  2.4L engine 5spd

The other day the car started to buck and sputter and the check engine light went on.
I put it on the OBDII. It had codes for camshaft sensor - after locating it (real easy to find)
and the parts store delivered the wrong one - I cleaned up the old one and the light went
out.  It started to buck again and the light came on again... I finally got a new sensor
and changed it. It hasn't bucked and sputtered anymore but...  Now my MPG is going way
down fast.  I have changed the plugs (with proper gap) and the boots... I still can watch the
needle drop -

What has changed??? What do I need to replace?  What do I have to do different?

My car of similar model (same engine, 1997 SE) did this to me and i found that two things fixed this for me. and that was fuel injector cleaner and a tank or two of premium, this happened to me after a tune up...
