I died on me today on the first "bounce". Any ideas? Thanks!

... cleaning the idle control valve, as was recommended above.

Happy Boxstering,

Thanks everyone. I am waiting for my Bentleys manual to arrive (just in case) then I will give it a shot and let you know the results.

You will find more useful information at Pedro's website then the bentley book (which is nice to have too)

Pedro's site looks great, lots of very useful info! And lots of projects I am definitely going to tackle. But I dont even know how to put the top in the service position, so the Bentley's is a must. It is my bible on my aircooled VW.
