The vehicle has 246k miles and burns alot of oil.

I changed the cat 4 years ago as I failed smog with my NO through the roof.


I purchased the vehicle in 2001.

The O2 sensor might be original. 4 years ago when I was failing smog I monitored the voltage and duty cycle with a dwell meter and it was operating fine according to the tech notes I found on O2 behavior.

I did get some factory non resistor plugs from another member on I believe a different forum that happened to live in my neighborhood. I Bout a large supply had extra stock and some me 12 plugs. I am still on the first set. These were installed along with a new cap and rotor and wires 4 years ago when I was failing smog.

Four years ago when I looked into non resistor plugs I recall hearing similar but also found the the dealers either had them or could get them and they were very affordable.


In the next day or two I am going to dig out the test results for the last 2-3 tests and see what my HC was. One interesting exercise would be to plot the results for each reading of all tests to see how things change every 2 years.

It doesn't start super easy like it use to , need to crank it a bit and the idle isn't as smooth as it use to be. I replaced the injector seals and 4 or 5 larger air / vacuum hoses. I do know that I have a leak at my intake gasket as I verified it by spraying carb cleaner on it as having the idle go up.



Thanks
