Yukon Gal -

Put fuel filter in after oxygen sensor and before fuel pressure regulator.
The filter is cheaper than the pressure regulator.  Before replacing the
regulator you may want to check your fuel pressure.  It's hard to regulate
low pressure.  Low pressure would indicate your fuel pump may be on it's
last legs.

Yukon Gal-
these are fairly common symptons... but lots of possible problems.
First place, keep an eye on your gas milage.

1) oxygen sensor. Unplug it and see how thing work. If it works pretty
good w/o it then that could be the problem.  ABout 30$ to replace yourself
2) fuel pressure regulator: you could be running rich. About 75$ to
replace
3) temp2: computer could think you are running cold adn therefore give in
more fuel. About 40$ to fix.

All of these things are easy to fix and fairly easy to diagnose with the
help of the bentley manual or The List.

cheers
Matthew
