Dad, if you can post the code definitions I would be curious to see
them, I have a small reader and booklet that lists some that are tied
to 'blinks' that give you some information but I don't think it is as
comprehensive as what you are talking about.
Perhaps you could send them as an attachment to me via e-mail of
perhaps an FTP? As to the fuel pressure on these cars, monitoring that
would be as simple as the oil pressure light on a 56 Buick, just turn
it on if pressure falls below a certain value.
I just put a fuel filter on the car, it made no difference. After
experimenting some I am able to keep the car running, (sort of) by
careful throttle positioning so that lets out oil pressure switch
problems or a distributer not telling the ECM to continue spark.
Looking at the plugs it is obvious that the car is running EXTREMELY
lean, IMHO lean enough where engine damage could result from trying to
run it, which should be throwing a code too. Since this is not the
case I am beginning to think the ECM is getting a spurious signal from
some sensor that monitors the exhaust gas makup, or the ECM itself is
not functioning properly. As near as I can tell, there are no exhaust
There seem to be some setups that let you hook up a laptop to the ECM
and, along with some software, see what the ECM 'thinks' is going on.
Has anyone here used these setups on the L98 engines, and does anyone
have an idea as to the
pros and cons of the various setups? It seems like this would be a
very valuable diagnostic and tuning tool.
And a CBX
