There is an index or whatever it is referred to on the outside of the lower timing belt cover that is supposed to be used to check timing. On earlier models it is required that you jumper a couple pins on the Data Terminal Connector to remove any advance that the ecm might be giving it in order to check the timing. In the 2000 version the All Data says to run it at idle and make sure the timing is eight degrees to five degrees advanced and if not replace the ECM. When I throw a timing light on it it looks like around 25 degrees advanced, but I cannot be sure because it is way over to the left. I know the belt is right on perfect. What is the real truth about
that timing mark with the notches and the letter T.

Timing is not adjustable on this. Is there a specific problem you are having with the vehicle? If there is the "check engine" light should illuminate and the trouble codes should be read off.

Yes there is a problem, but I get no codes. The car behaves like the timing is all wrong. If I floor it it slowly climbs in rpm until when it is almost ready to shift and at that point I can feel the acceleration jump higher as if a cylinder just got added to the engine but not like it was just one cylinder more like every cylinder started working better all of a sudden. No codes, but I really just want the answer to what should I see when I turn on the timing light. Should I see it way up at twenty degrees advanced or should the little notches in the pulley line up with the timing marks on the timing belt cover. If I use a wrench to turn the engine slowly the timing marks line up with the notches on the pulley exactly perfect and the cam timing marks as well. What's it supposed to read with a timing light at idle? Also the book says the crankshaft position sensor should read between 2 and 3 volts at idle, but I only get 1.6.

Hey JOHNNICINCO,

You cannot adjust the timing on this car. It sounds like you have an ignition problem, have you changed the spark plugs lately? if so you may have an ignition coil that is failing, I would replace them with new, here is a guide to help test them.

and for the spark plugs

Let me know what you find,
