Do a search and you will find information on how to check your "WUR" Warm Up Regulator.

I have just joined the Rennlist forums, as I saw this thread. I have a similar problem (it's not a clear misfire but what I term an "uneasiness" occasionally under high load too). The two components under the most suspicion in my mind are the 1. the cat (which is U/S and not flowing well) and 2. the leads (which are within their resistance range but are at the wrong end of the range). So I would be very interested to hear if your mechanic found and fixed the problem.
Cheers,
Iain.

I had an issue with similar symptoms when I first got my 'new' Turbo 3.6, replacing the secondary fuel pump solved it. (See an earlier post by Turbohead suggesting an investigation along the same line).
