So I had a question about my obersvations on the timing light use. I bought a Craftsman Advance Inductive Timing Light. I painted a line across the pulley so I could see the timing mark clearly. The white line seemed to jump back and forth at the 5 degree timing advance on the timing gun dial. But when I put it at the 0 degree timing advance, the white line seemed be stable and to not jump around at all. So to check where the timing is at, should the light be making the white line seem sold and stable? If so that means I am off and at 0 degree timing advance. How would I correct this and get the car to the 5 degree timing advance it should be at? This is my first time using a timing light. When it jumps around it is on the 5th tick mark from tdc. When it stabled out it was at the 2nd tick mark.
 
Leave the timing light set to 0. You don't want the light adding any advance.
You want to find the timing mark on the harmonic dampner and the mark between the T and 10 on the timing belt cover. That's 5 degrees BTDC.

It's been awhile, does a '96 MY 2G have a CAS you can adjust?

Steve,
Which plug is the timing adjustment plug? I see a blue plug, a tan plug, and a black plug. Also where is the CAS? There is no sensor on my left side of the valve cover, side oposite of the CAM gears.

I don't know which color. On a 1G it's the larger black connector, that on a unmolested car has a dust cover.

That's what I asked. You can check the timing but not do anything about it but replace the sensors. The cam angle sensor is attached to the fron intake cam gear and the crank angle sensor is attached to the crankshaft and the front of the block behind the crank sprocket.

So the only way I can set my timing is at the crank and making sure it is at 5 degrees advanced timing then? I am asking because when I did my first log, my timing at WOT is at 3 which is really bad. I have my car running really rich so I don't knock. What else could cause my timing to be so bad at WOT? Here is my log in case you want to look at it.

What I'm saying is that you can't set your timing at all, only check it. If it's bad you can replace the sensor and trigger plate but not change your timing from the factory setting.

You can create knock by being overly rich.

Well, as much as I don't like to do this. I think I am going to have to take my car in. I just don't really know what I am doing and I can't risk making a mistake on this one. At least it is only going to cost me $45 to have everything checked.

Steve,
I took the car into the dealership. They said that my knock sensor was completely gone. Wasn't working at all which is what has been throwing my timing off. So I will be putting a new one in tonight or tomorrow and I'll have to see how things go from there.
