Check to see if the valve lifters are not making the noise. Turn on the engine and rev it up to about 1500 rpms and see if the clicking is coming from the valve cover area.

I have encountered this problem also, try changing your battery. My battery lasted almost 4 year till it was the cause the shot my alternator.

My '91 626 did the same thing. I tested the throttle position sensor, and it was good so that wasn't it. The other likely culprit is the Idle Speed Control valve, or Idle Air Control valve, which is a $500 part new (more than I paid for the whole car). I pulled one off a 626 at the salvage yard and got it for 3 bucks, put it on (it's an easy DIY, just 4 philips screws holding it to the intake manifold), however I can't be sure that solved the problem, since I haven't run the car much since then. It would seem the most likely cause, tho, and a cheap fix if you go used. Other possibilities: O2 sensor or Mass Air Flow sensor?
