Buick Mass Airflow Sensor

I have a 1989 Buick LeSabre T-Type with a 3.8
liter V6 FI engine. My problem is that my car
sometimes gets that rotten egg smell. I had my
catalytic converter replaced a while back in order
to pass DEQ, but it still smells bad on a
consistent basis. Also, it runs really, REALLY bad
when I do not warm it up for at least 5 minutes.
If I just get in the car in the morning and drive,
it seems like I have NO power at all. It will take
about 10 seconds just to get up to 20 MPH. The
funny thing about this is if I get in the car
without warming it up, and then floor it, I get a
HUGE surge of power which makes the tires peel out.
After that though, it goes back to being slow
until I drive it for about 10 minutes. I have
spoken with a few of my friends that know
"something" about cars, and they seems to feel that
it's my mass airflow sensor. If you have some
advice for me, I would greatly appreciate it.

Your host, Bruce.
It's located on the tube between the intake
and the air cleaner. With the car running, tap
the top of the sensor with the handle of a screwdriver.
If the car tries to stall when you tap it, it's
bad.
