Re: Timing

On my "89" TBI its =
Start car and idle until the car is at operating temp. Disconnect the EST wire, adjust timing, reconnect EST wire. Shut off car .


This is what the EST wire on my car looks like with a brown wire with black stripe.
Its over near the blower motor.
( EST = Electronic Spark Timing )

You might need to also set " Minimum Idle Speed" when your done.
