How is the oil level. Low oil can cause low pressure at idle and when cornering, and is a VERY bad thing.

Has the oil filter been changed recently? It could be causeing a problem, but I've never heard of it doing anything like what you're describing.

 

Also, does the engine burn or leak at all? Those could be a sign of low pressure once the motor warms up. Have you tried a thicker oil? (It would only be a temporary fix)

Is the water pump physically moving the water? If you have air in the system, it will cause a bubble right before the water pump which will block water/coolant from entering it, and thus the engine. This problem will also be more severe at low RPM (See: Idle) as the pump wont be spinning as much as it does at higher RPMs, such as those on the highway.
Never shift into reverse without a back-up plan.

Did you see my earlier post?

Take your hand and feel the coolant pipes along the bottom of the car and feel for any crushed areas in the pipes.      To get a rough idea if the water pump is working.  Remove the rear coolant cap, fire up the engine, water should SHOOT out of the filler neck. If it does not move much at all, the pump is shot.

I am sure the good doctor could squeeze you in, even if it is just to confirm what the problem is.   Not sure how much time he has, as he is swamped with work right now.   He has a small home shop in West Surrey / North Delta.   A few blocks from Scott road in Surrey.    Drop him a PM and I am sure he can help ya.

And as with most Dr's....  I don't usually make house calls, so you'll have to make it over here.
