I drive up and down the Mount Washington road every day and tried Nokian WR this year. Used to run Blizzaks. WR's are the best grippy tire I have used. Also rated at 100,000 Km's so don't need to swap em off in the summer. Now all my buddies have em as well.

Been there done that. Helps a bit , very messy and smelly.

Yes it is fuel injected. I just wondered as it did not seem to affect my fuel mix on the way up the hill today, ie: no pinging, usual power, no smoking from too rich a mix. The sensor is $89.00 canadian up here which is affordable unless I am throwing it away for naught. I have not tried paint, just cheap muffler and pipe makes it 175.00 every other year.

I have a 91 loyale that I use strictly for getting up the ski hill in the winter. The exhaust system has had the Catalytic converters removed and runs a straight pipe to the muffler as the system is replaced every other year due to rust. Now my check engine light has come on and the code says it is the O2 sensor. Do I even need this sensor without the Cat converter's? Performance did not change at all since the O2 sensor quit. We have no emissions testing here so that is not a issue. Is there any reason to replace the sensor other than getting the light to reset?
