Yow! The problem comes from when you apply "The PEDAL TO THE METAL OR
MASHING OF FOOT." Hehehehehehe Sorry!

I usually replace the 02 Sensor every 10-15K based on the aftermarket
additives and so on. Usually, the sensor will last at least 15K or longer
with normal driving habits.

Spark Plug wires are replaced every 20-30K if you do a lot of street racing
and using high output ignition systems.

Yes I know. The factory manual says it differently.

Whenever you are replacing timing parts, go with the better brand name and
not the cheap items. A good example is the tin metal used in distributor
caps that will easily burn out with HO coils. Go with brass units.

Subject: DML: So... How long do O2 sensors live??

The title pretty much says it all.
My 99CC 318 seems to have been gradually losing it's fuel efficiency over
the last 5k or so. I remember talk on the list some time ago that o2
sensors gradually lose their reaction speed over time and are best replaced
at 60k or so. Yes/No?? My Dak has 51k miles now.
The mileage loss is despite plugs. cap, rotor, plugwires, TB cleaning etc.
Any ideas other than the o2 sensor why my mileage is goin south??

Thanks
Ken
