There arent any re-learn procedures on those vehicles
and the ones that had a re-learn procedure was just
for the idle anyways. The first thing you should check
is for any dtc's. If it doesnt have any power there is
probably something serious enough wrong to illuminate
the ses light but Im sure it's possible that it might
not be illuminated. I would imagine that it isn't
missing since you didnt say anything about it so that
should rule out a regular tune-up item such as plugs
or wires even though it wouldnt hurt to check them.
More than likely from what you tell us it sounds like
there is something wrong in the computer or sensors
but a general check of the engine would be a good
idea, just look for any loose connectors or vaccum
lines and/or vaccum leaks..................Phil
