I have been checking my fuel mileage(3 times so far) on the HHR and each
time the computer gives about 1 mpg>  more than what I figure. That's not
too much of a difference, but am wondering which is the more accurate? I
would think that the computer would do away with differences ...

I recently rented a SS Impala from Alamo.
I forgot how much fun it was driving a V8 sedan!
Instant acceleration on the highway, no constant downshifting when hitting a
slight upgrade, passing is as simple as can be.....BUT....

I noticed yesterday that Mobil has come out with fully synthtic 0X-30
Oil. They claim it would save you more money as far as gas mileage
goes. Just wondering what others think of this, and how safe would it
be to put into a older vechile.

Jaguar and Land Rover are being sold by Ford to Tata Motors of India.  Who'd
have thought it?

I have a 1996 Buick Century with electric windows. The two front
windows (driver and passenger sides) will not operate at all. Does
anyone know if this could possibly be a fuse or something else, like a
relay.

My 95 Pontiac GrandPrix with 3.1 is surging.  Not bad, VERY subtle.  I
have no error codes, other than EGR (I know I have a clog) but the surge
is under light acceleration, and the EGR shouldn't affect that.
Anyway, I'm gonna try a soak-out of the EGR this weekend if the weather

2002 Monte Carlo 3.4L  but more of a generic question
Owners manual says spark plugs are good for 100K....  Platinum plugs...
I just replaced mine at 57K,  they looked not too bad,  a little worn. But

The battery in my 2001 Monte Carlo has a fitted foam insulator the surrounds
it on the sides.  After all these years the insulator has seen better days.
I'm replacing the battery.  Should I acquire a replacement insulator?

When I start my 07 Malibu SS at about 1/3 up on the heat scale, and
then at about halfway, the car makes a sound which to me sounds like a
"muffled" backfire.  It seems to occur when the car is being driven
fairly slow.   I don't usually warm the car up much: I just wait a

Hi everyone, I was hoping someone could enlighten me on the subject of
the latest UAW-General motors contract. The thing I don't understand
is the two-tier wage's. From my understanding new "non-core" hires
will earn around half that of current assembly workers, around $14,

"Newfound reliability has dealers losing money on warranty work.
The National Automobile Dealers Association estimates dealers
currently lose $30 on every new car they sell
They make up the difference through financing, add-ons, service and

I did it !!   Finally finished replacing the lower intake manifold gasket.
Not an easy DIY job for the first time,  especially on an engine I've
never worked on before,  but I can see how it would be pretty
quick after doing two or three.

My 94 LeSabre once every week, or every two weeks, stalls. After 10 or 15
minutes it starts again and works normaly until the next time. At the time
it guives the engine codes 361 and 321, but when working normal has no codes
present. I don't think is the ECM because I ...

I know this has probably been on here a hundred times before, but can anyone
tell me the procedure for entering the program mode for the remote door
locks and the procedure for programming them? I had one go bad and got
another on ebay now I need to set it up. 2002 Chevrolet Venture ...
