How to set the timing on a 1997 350 Chevy?
you don't the ECM will do it for you. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx You need to set the base timing on any car/truck that has a distributor. There is a tan/black wire that is usually under the dash down low on the passenger's side. This is the Electronic spark timing and the connector has to be apart to set the timing. That will put the computer offline while you set the timing to the specifications. There is usually a decal under the hood. Once the timing is set then reconnect the connector The base timing is set NOW the computer will take over from there.
