Does anyone know the proper procedure for setting the timing on a 4.9 six? The Emissions decal under the hood says "Timing is electronically controled and not adjustable" but the distributor has a normal clamp down.
The van pings bretty bad and I think someone may have played with the adjustment.
The distributor has a pickup in it as well as there being a crank angle sensor on the dampner. Plugging in a scanner to the OBD2 port I can see the timing advance is 10*, If I turn the distributor I can get the timing to advance on the scanner but I can't get it to retard any less then 10*. One manual says to disconnect the SPOUT Connector but there is none that I can find and this info is usually on the Emissions decal IF the timing is adjustable.
Anyone know the dealer or factory set up procedure?
Follolw the wires coming off of the distributor, all the way to the ignition module, there should be what looks like a jumper in one wire, pull it out, set the timing with a light to 10*, then clamp it back down. It may also be in desperate need of a tune up.

I was able to locate the spout connector near the TFI module on the fenderwell unde the hood and the timing pointer is on the opposite side next to the crank sensor with the degree markings on the damper.
Set the timing to 10+* and no more pinging.
