   Aug 14, 2007 - I borrowed a friend's 2002 Oldsmobile Bravada to pick up some supplies ... The Electronic Controlled Air Suspension (ECAS) compressor was running,... I found the compressor check valve sticking in the compressor housing ...

aircon units and the passages,vents etc can grow mould etc in the warmer climate due to the dampness left behind by the a/c working.you need to use the aircon more often.buildings can get legionaires ******* in their cooling towers,so its quite a problem.you could try a vehicle sachet of some nice smelling stuff to hang on yr inside mirror for a while,and see if a/c use will kill the bugs

Try balancing tires.

when these begin to leak the only solution is to replace

Sounds like a relay or the low pressure switch.
Does the blower work but no cold air, or no air at all ?

I WOULD SAY YES BECAUSE THE LUCAS FUEL INJECTOR CLEANER IS JUST HELPING THE INJECTOR SPRAY BETTER

Strong smell of gasoline fumes means that there may be other issues involved than the O2 Sensor.
If it is enough of a smell that you believe gasoline is leaking in the engine compartment, I would not drive the car. The catalytic converter goes up to over a thousand degrees under the car after it is stopped. If vapors accumulate in that area. You could have a fire. NOT SAFE !!.
I would have the car towed to the nearest reliable service facility if you suspect a leak.
If you are working on the car yourself. Open the hood, pull the air cleaner and look for leaks in the fuel injection system. Along the fuel rails and where the injectors go into the manifold.
If it is just flooded then that could have something to do with the O2 Sensors. Please, use caution.
Hope this helps,
Mark

When driving it , or just sitting idle ????
