Engine 3800 V6.
Check engine light blinking.

Just bought it on July 3rd, used. My check engine light is blinking, a white cloud of smoke came
out the back, and now it won't start at all.


Answer: A flashing
check engine light is an indication of an engine misfire that is bad enough to
cause catalytic converter failure. This is different from a solid light.

The fact that there was smoke, and now it wont start leads me to believe that your problem is with
what is called the Upper Intake Manifold Plenum. These fail internally and let coolant enter the
intake system, causing misfire, engine light, and worst case- the engine wont turn over or start.

A way to check is to have the cooling system pressure tested, or remove the
spark plugs and look
for a cylinder / cylinders that are full of coolant. A cylinder that is full of coolant will not allow the
engine to turn over- it is called "Hydrostatic Lock" and can be confused with a totally locked up
engine that needs to be replaced.


2003 Buick LeSabre V-6 Service Stability Control warning light on.

I have a 2003 Buick LeSabre with 170K miles.  In the last month the Service Stability light has
come on more often, BUT more importantly there is a loud humming sound when the vehicle is
turned left and right during driving.

Also, there is a small leak (not oil). The stability light has been coming on/off for over a year...so
I'm not worried.  I NEED TO KNOW WHY THERE IS A LOUD HUMMING WHEN TURNING LEFT
AND RIGHT.  ALSO, is the humming and leak (not oil) related?

Answer:
The two problems could have a common factor, or be completely different. Just saying the leak is
not oil doesn't give much idea to what else it could be.

A likely problem that would cause your humming noise while turning would be a power steering
leak. Depending on the age of the power steering fluid, it could be clear to very dark. It does have
the same consistency as oil, though.

A leak there would lower the level in the power steering pump reservoir and would result in a
humming/whine type noise when turning the wheel.

If the noise only happens while the car is moving, or at speed, it is most likely a wheel hub bearing
that making the noise. That would also set the service stability light on. Either problem would need
checking into.
