Impossible to read handwriting about problem diagnosis. A friend using my car got the 'check engine' light on my Geo Metro. G&J Shell plugged in the fault code reader, returned 'code 51', scrabbled 4 lines of 'diagnosis' on the work order form, that are impossible to read or make a sense of. The only clear thing is the charge of 75$ (PLUS a 2$ charge added w/o explanation on the VISA receipt). This station isn't near so I won't go there to get a 'translation'. Quite a waste of money.
