[Shotimes] HEGO sensor trouble codes

[Justin Schick]

I was under the impression that Bosch made the Motorcraft ones. But like
I replied about your IAB, just because it's new doesn't mean it's
working correctly.

I've read elsewhere that HEGOs never really "go bad", and to refresh
them you just have to soak the tips in carb cleaner to eat all the caked
on carbon junk off.

It could be possible your car really is running rich. How old is your
thermostat? It's a classic rich-running culprit. Have you checked /
cleaned the MAF wire as was suggested in the last thread?

I talked to a Ford technician yesterday about a stalling problem and
HEGO
trouble codes (17*s).  He thought that my sensors were bad
(aftermarket
Bosch-1month old) and weren't switching fast enough, since the codes
are for
reading lean and rich.  He suggested getting Motorcraft ones instead.
According to him, he's seen this several times when aftermarket sensors
are
used.  Any thoughts?
