Hello All. Thank you in advance for your help. I have a 93 Sunbird 185SS with a 3.0L GM OMC Cobra. It was doing wierd things so a mechanic friend adjusted the timing. Bad mistake. So after reading from the SELOC online manual, it requires a timing shunt to compensate for the changes the icm module makes for the adjustment. Does anyone know how to make one? I tried my only local OMC repair facility and they were of no help. Thank you again for the help.
