Matrix owner questions...

sounds like the transmission is kicking out of overdrive or going into
the next lower gear. both or normal.

Dave says what I was thinking, but a bit more info is needed. Do you have
the AT or the 6-speed? If you have the AT, now would be a good time to
drain and fill the tranny, if you haven't already. I would say just check
the fluid, but a tranny service might be in order. If you don't want to do
this yourself, then check the fluid according to the manual and top off if
required.

If you have the 6-speed then things might be a bit more drastic. It sounds
like the clutch may be slipping; when going uphill in 4th gear, does the
engine start racing with no increase (or worse, a decrease) in speed? If
so, you may need a clutch replacement, but I can't really see that unless
you are REALLY hard on the clutch!

It is difficult to say what the cause is without actually experiencing the
condition. A slipping clutch will generally get worse, and the engine will
not return to normal RPM without backing off of the throttle.

Check the engine air filter to make sure it is not clogged. Check the black
plastic intake tube between the air filter and throttle body for cracks or
holes. Carefully remove the MAF sensor at the air filter housing outlet and
take a look at the wire inside the tube that sticks into the air flow. The
wire should be clean - if it is coated with dirt, clean it with carb cleaner
or rubbing alcohol. Be very careful not to break the wire or you will be
looking to spend several hundred $ for a new sensor.

Live near any big hills? Esp on an Interstate. Go up the hill as normal,
and press your foot on the gas to keep up speed, in 4th gear. If the tach
starts climbing with no increase (or a decrease) in speed, then your
clutch is most likely on the way out. Or, on a straight level in third
gear, press your foot on the clutch slowly and make a note on the rtach
when it starts to climb. If it's less than 3-4 inches, there's something
going on.

It may also that the cylinders (master and slave) need bleeding.
Also, check what Ray O said. These can be done by yourself in the comfort
of your own garage!

I tested my car as you suggested and this is what I noticed. It seems
to only lose power as I previously described earl in the morning, when
the car is cold. Lately, down here in Southern California, the
mornings have been between 45 - 50 deg. Not that cold but cold enough
for a sitting engine.

Once thr engine is warmed up, I don't notice a decrease in power as I
described.

After re-reading your first post and this one, it does not sound like a
clutch problem because clutch problems are not temperature related.

I'll stick with what I recommended before:

Check the engine air filter to make sure it is not clogged.
Check the black plastic intake tube between the air filter and throttle body
for cracks or
holes.
Carefully remove the MAF sensor at the air filter housing outlet and
take a look at the wire inside the tube that sticks into the air flow. The
wire should be clean - if it is coated with dirt, clean it with carb cleaner
or rubbing alcohol. Be very careful not to break the wire or you will be
looking to spend several hundred $ for a new sensor.

I understand why you think 45 ~ 50 degrees is cold. When I moved from
Chicago to San Francisco, I used to think that the people wearing down
jackets, hats, and gloves when the temperature went down to 60 were wimps,
since that is still T-shirt and shorts weather to a Chicagoan. After about
a year, I had become acclimated to the nice California weather and joined
the ranks of wimps wearing winter jackets when the temps dipped into the
60's.

cold... About two years ago, I visited my in-laws in Green Bay
Wisconsin. I was raised in Southern Ca. That was a new kind of cold for
me - *bitter*. I now have respect for GB Packer fans.

thanks for the tips. I'll try not to destroy my engine. I keep wanting
to sell my XRS and then I change my mind when I drive out around. I
really, really like this little car.

They are AWESOME! Same output as the Celica, 6-speed tranny, and a neat
little wagon to boot. I got to drive a couple of XRS' when I was working
at a Toy dealer last year, and they were something. I think '05 or '06 was
the end of them IIRC...The best you can do now is an XR

In case you'll be needing to replace some of your http://www.autotoyparts.com/toyota-matrix-part/ (Toyota Matrix Parts), I know a site that could help.

Just wanna share.
