Hello Anders,
So, please, any help about this problem will be really appreciated.
I have it, José, though for a 2001. I bought the book off eBay in france some years ago and it's sitting on my bookshelf. I'm horribly busy though, but as another Espace owner has asked me to copy some pages from the book too, but there's a lot to copy since you need the index pages too (components are numbered, not named on the diagram).
And I don't think the diagram will help you. You can check the wires with it, but the problems you describe doesn't sound like bad wiring/connectors etc.
I agree with Roy that the fact that the problem is now worse may actually be your luck.
My garage would probably take the car, leave it running for a few hours with the diagnostic computer connected, and carefully inspect what happens on all the sensors.
We did it once with our 24v and found the water temp sensor to be defective. That was our cars' problem, yours could be different: fuel starvation/pressure, sensors, oxygen sensor, TDC sensor, ignition coils etc...
I think you should go back to the garage. I know the money part isn't fun, but it's really your best bet.

Well, let me explain a bit more my idea... yes, I know it is NOT a wiring problem, as it is very predictable and repetitive. But I want to know which sensors system uses and, if possible, where they are located, in order to be able to do some work by myself. Problem with garage is not only the cost. Is that they are plainly inepts!. It may sound hard but is the truth
My background as Telecommunication Engineer and my experience repairing electronic items will sure help here. I plan to view / record sensor readings, aided by my stash of test equipment gear. I am sure I can find the problem, but need some info and time. Later one is OK but first one is, by now, missing.
So, please, when you have some time, I would appreciate a copy of the needed information. We can comment this off-line, if you wish. My e-mail is: eb5agv<at>ctv<dot>es
Thanks a lot!
