Thanks for all the answers to my questions!!! I love this board (seems like there are many new people here, great).

No one really answered this question though...

When I come to a fairly quick stop, the engine dies/stalls. Clutch is in, and downshifting is a pain/difficult with the way the syncros are. What's up with that? Why does the engine stall like that?

Anyone ever driven the "Going to the Sun" highway in monatana??? Heard it is amazing. Has anyone driven their cars in the mountain (rockies). I drove to from Calgary to Vancouver a few years ago in a fuel injected jetta. The car struggled some through the higher passes, and I am wondering how a 25 year old 02 might function in a similar situation. Previous owner of my car tricked it out a touch with a shrick cam, and the weber etc... this performance stuff tends to make my car a pain in the ass to get fixed/keep running smoothly and it seems to need more tending to than a more "stock" 02. I think my problem is that I am living in an area where no one drives these cars...

The stalling thing is likely a carb problem, or a composite of "state-of-tune" issues (e.g., carb, valve lash, ignition tuning combined). I think Rob S. is right in that the direct cause is the snapping shut of the throttle, possibly causing a non-optimal mixture situation in your carb. When you think about it, what is happening when you engage the clutch and close the throttle is that you are phasing between the main and idle jet circuits in the carb.

So, you may want to make absolutely sure your idle mixture control is adjusted properly. Also, at what RPM does your car idle? S/B 800-900 RPM. You can't go by the tach in the car- you need to attach an accurate tach to your motor to determine true idle speed. If it is low, it will be more prone to stalling. Even if you can't figure out what is causing the stalling problem in the short term, bumping up the idle a bit may at least treat the symptom so that you can take your trip and not have the hassle of a stalling motor.
