ECM fault?

[Akselrud, Boris]

I am talking about GM part, it's $500. Like you said, don't put anything non
stock on the car.

	I've checked this out too at some point. I even went as far as
checking
	pressure in exaust manifold. I don't remember the figures now, but
it was
	almost non existant comparing to the numbers in the service manual.

	I am pretty sure that there are no holes in the exaust system.
However I
	have doubts about catalytic converter. Exaust sounds kind of loud
and
	humming at some RPM. Could failure of catalytic converter cause O2
sensor to
	misbehave and react slowly? I've been through this hypotesis before,
but the
	problem is that to test it I need to put a new catalytic converter
in, which
	is not cheap.

	Yep.

	Another thought is an Exhaust leak at the manifold.
