It retards the timing so the engine is easier to start. After it starts, it advances the timing back to an advanced position for best engine performance.
There is no such thing as a timing advance wire on a 84 El Camino.
AnswerMost of the time, the steps to take to set the timing are on the catalyst sticker under the hood. But first, you must get the vehicle into base timing (usually disconnect a wire from distributor). Remove distributor hold down bolt, hook up timing light to #1 spark plug wire, start engine, and align timing mark (0°) Once this is set, reconnect the wire you had to disconnect for base timing. Timing advance will automatically set itself. if it doesn't, you have a faulty timing advance mechanism on the distributor. You can check timing advance by pointing the timing light at scale (while hooked up to #1 spark plug wire) and rev the motor. Timing marks should move up the scale.On many GM cars and trucks the wire that you disconnect is solid gray in color, it is in the wiring harness on the firewall, the wire has a black plug for separating when doing the timing.
You have to unplug the distributor advance wire, it's a tan or brown colored wire, set to 0 (or up to about 8 advance) then reconnect the wire.
It will be a tan wire with a black stripe that breaks out of the wireing harness on the fire wall but close to the dist.
buy a timing light. clip it to the #1 plug wire. loosen the bolt on the distibutor. Unplug the timing advance. start the engine Point it to the harmonic balancer and turn the distributer until the timing mark on the timing cover lines up with the mark on the harmonic balancer. Tighten the distibutor bolt. plug in the timing advance.
unplug the wire that says tach on the dist cap that's the one that reads rpm do this while car is off if this wire is unplugged it will not tell the computer to advance or retart the timing then set your timing to 8 degrees tighten it up and plug it in and that's how you set the timing
It's a brown wire with a connector. It's located on the firewall on the driver's side to the left of the power steering booster. Pull the connector apart before checking the timing. Be sure to re-connect afterwards.
No
disconnect vacumn advance hose, bring down to curb idle, connect timing light to the # 1 spark plug wire, loosen distibutor and adjust as necessary
Emmisions sticker under hood should have timing setting try 8 before the wire is a single connector look in the plastic cover on top of firewall that holds wires going across it
The vacuum canister can advance 24 degrees beyond initial timing.
The ECM does. The module is only a pickup and a signal conditioner. There is a tan wire with a black stripe that disables timing advance when disconnected, so maybe that's whats going on. Its near the realay center on the firewall.
