Recently, the "service engine soon" light on my 95 GMC Jimmy came on. I went to both Advance Auto Parts and Auto Zone who were more than willing to run a diagnostics scan for me (free).
Unfortunately, they couldn't get a diagnostics read because my truck is so old. They recommended I call Pep Boys. I called Pep Boys and asked them if they could run the diagnostics. They informed me it would be no problem ....
and it would only cost me $94.00. A new diagnostics tool is only $129.00 !!
What a ripoff !! I can guarantee you I will never darken Pep Boys door again
