1992 Chevy 350, you need to unplug the brown wire under the black cover on the pass side firewall. Then make sure its timed on 0 measured at the front of the damper. If it does not run right take off the dist cap and with a socket and long breaker bar have someone watch the dist rotor as you turn the engine reverse rotation, what you are looking for is a slack in the timing chain. If their is significant slop, then retime engine 2 degrees advanced til it is running good again. When you are done reconnect the brown wire and put the plastic cover back on. Done.
