[V8] exhaust soot

[Michael Larosa Jr]

sorry ingo,   I have no idea about part numbers since my V8's and the manuals
have been sold years ago....


but I do remember that when the head temp sensor went kaput i had black soot
coming out and got nasty gas mileage...  once i replaced the sensor it ran
better but didn't run 100% till i swapped out the new 02 sensor i had just put
in on my first attempt to fix the soot :)
