Hello,

Today I was trying to check my ignition timing. I followed the procedure in the Haynes manual of jumpering the connector under the glove box.

But when i jumper the wire the timing marks on the crank pulley arent within the limits of adjustment by turning the distributor!!!! I then checked timing with the connector unjumpered, and there is no change in apparent location of the markings!!!

The camshaft timing is right on (i did a sanity check by taking the upper timing cover off and checked for the alignment with the white mark on the crank pulley) and its right on. Also the car runs very well, not stumbling or anything like that when the timing isnt right.

What could cause this? Is there something wrong with my ECM?

Thanks!

 

Would your idle speed make a difference?

 

I talked to some buddies at work and they had the thought that idle speed might be affecting it (the spec says idle at 650 RPMs, my car cant get below 1000 right now) and the MAP sensor might be throwing it off too...

Any other ideas?
