No longer need this scanner and have all cartridges to do up to 2001 with it. only have the gm obd1 connector and can get the obd2 off ebay for 20 bucks. the cable had been giving me fits and sometimes not reading so I cut it up and fixed it and a wire broke again. ebay has them new for 14 bucks so either fix the cable or get a new one. I am asking 300 for it and it all works great and is very clean(other than the cable. has trouble shooter for engine and transmission stuff. Will do any domestic vehicles from 80 to 2001 with the right connectors. So much easier to tune if you have a good scanner and one that can do some recording which it will. P.m. if intrested. It is listed under parts for sale but had no hits so figured someone tuning might have a problem and cant get help if you cant give data to people.
