Re: O2 sensor

[Alfisto@domain.elided]

Just had a long chat with Roger at Roger's Autoworks re- my problem (after 
Ron at Camissa was of little diagnostic help). Roger knows 
Alfas/smog/ignition well and concurs that it is doubtful a bad O2 sensor and 
in 30 years has rarely if ever, seen one go bad. Would also cause Check 
engine light to go on plus strange codes etc which mine does not do, and 
motor to run rich (which mine does not). Suspects high humidity causing 
ignition problem and coils to short and act act up (which they do). So, next 
job is to remove junk from rear bank and check/change the coils/plugs, and go 
from there. Doubt if its the coolant temp. sensor although mind you it just 
might possibly be. I changed it a year ago, but for a used one, and ever 
since then, the red light went on and stays on 90% of the time. Might just be 
a bum one. Everything is so darned inter-related in these cars that one thing 
affects another which..... I just may start off by getting a new one of those.

Now if only I knew why my 74 GTV did not pass smog today - its last test 
ever! Probably those darned 1750 cams... One thing after another.....
