I have a 2002 grand Prix. It doesnt have any get up and go. When I
floor it, it bogs right down. I changed the fuel filter but it made it
worse. I had it put on a scope at two different places and nothing came up
because the check engine light is NOT on. Could it just need a tune up?
SF:
Hello. I think I can be of some help. A couple common things. 1- The fuel pressure should
be checked to see if that is the cause of your problems. 2- Mass Airflow Sensors can also
cause this problem but would have a code stored. 3-The most probable cause by reading
your condition is that the catalytic convertor is plugged. This is a very common problem.
That also should have a check engine light with a code p0420, but not always The good
news is that GM has a special policy adjustment for a failed catalytic convertor. It is under
warranty for 10 years or 120k miles. The special policy adjustment has a GM policy
#05551. FYI, a catalytic convertor replacement job at the the dealer would normally cost
$400-$700. Hope this was helpful to you, SF.
