Re: "Gross polluter" '91 200Q -- help!
Let me go out on a limb here. Why don't you replace your oxygen
sensor and spark plugs? You can send me a check for the
consultation. : )
My sister used to live in Denver. That's the only thing we ever did to
her car to make it pass when it failed the first try and it always passed
Another suggestion is to change to thicker oil. Run 20W/50. It won't
burn as bad, leading to a better HC reading.
One more possibility is a contaminated catalytic converter. I would do
in this order.
spark plugs and O2
Just my .02. I could be full of BS.
Oh, one more thing. possibly needs cap, rotor, and/or ignition wires.
Paul Anderson:Please send any direct mail to my private address as I
keep up with the list very well.
