Am back with Test results & code #'s, Now What ???
The car's computer says that everything is fine & dandy, passed the 2 tests, egnition on & enging on.
However the computer did remmber the last fault error Codes, which were 172 & 176
the book says 172 is the HO2s sensor is running lean, and the 176 code means the HO2s sensor is or was running lean Allways.
So I had cheap gas, a beautifull warm day and a lean HO2 sensor, what's the next step ??
Thanks for your inputs
