95 Mill wont give me any codes!?!?!
 

First hi to all. Ive got a 95 S that runs like crap. The CEL is on but the scan tool says that it isnt connecting with the com port? It is a new model scanner that is compatable with the older protocol so who knows? Motor has rough idle when warm and wont idle when cold. If you get the rpms above 3.5k power kicks in as normal. On decel there is a high pitched noise from the supercharger boost bleeding off but Im not sure where its coming from. Im mainly trying to get the codes pulled and then I can figure the rest out. More than likely a vacume leak but I want to make sure. Anyone know the fix to get the OBD II port working again?

Did you get yours to communicate with the scan tool ?
I have the same problem Now Mine is a 95 No Supercharger.
Any suggestions.
John.
