The ECU sets the timing. To adjust the timing you need to get the ECU in "Timing Mode" or the timing will be all over the place because the ECU is continuously adjusting it.

Here is the procedure.

Thanks guys. Well, the problem I have is that the dist is already at maximum adjustment. If I adjust it down some, the car will not even run. This would leave one to believe the timing is off, but it isn't, I just did the timing chain myself and I know that all the dots lined up. I drove the car hard, and the catalytic convertor was glowing red, so I know that the timing problem is causing it to run real rich, throwing raw fuel into the cat.

It has a new dist. I am thinking about taking it back and getting a replacement because maybe the dist is bad since it seems to be the only other thing that could cause the problem.

I will put it into timing mode as suggested though so that I can rule out any ecu problems and concentrate only on the dist.

to summerize though, there are no other sensors that affect timing?

Thanks a bunch

If you check the timing by setting the ECU in timing mode, and the distributor is still at maximum adjustment, this is usually due to the timing chain skipping a tooth or two on the exhaust cam or being improperly installed.

Is the timing varying because the computer is trying to keep it from stalling? and will putting it in timing mode prevent the ECM from making ANY adjustments?

BINGO!!!!
