I would try Tim Lamont at ACT products. He can sometimes get re-con ones. Failing that you could take a chance on this one...http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=27379&item=2492654880&rd=1

I'll try and dig out a receipt for a company that will send you one as a hire one, then if faulty you pay the balance. THey did this with my 350's ecu and it only cost @ £160 to buy, but they sent both afm and ecu just in case

Hey that would be useful - its something on the lines that i wanted to set up between us all (without the hire charge) - what sort of items they got Wedge related?

Ok found the reciept - 2 years old so hope the company is still there

Allcar Electronics 01773836485 Alfreton, Derbyshire

Still a listing in Yell so maybe able to help

Quick turnaround from what I remember with me thinking it was the afm, got another one and still had the same problem, then ordered the ecu which cured it all.

Although it's probably a RR one as was the old one according to the cover and part number, but the car still goes well and I did not want to pay £1000 one of the previous paid for an ecu

I think the answer is in the question. If it's a 2AM it's probably the Jaguar AFM, a larger bore unit that wasn't original on the 350. It will tend to make the mixture weaker unless you can up the fuel pressure.
Check the air hose coupling: if it's around 80mm bore it's the larger bore unit. The 350's was 70mm.

ask wedgie how to sort it out , as i had that same problem and checked the throttle pot readings which were ok and then found an air leak in the plenum chamber , the airflow meter were changed just befor i bought the car so i dont think it could be that although i do think a second hand afm were used , it seems that getting the right readings from the throttle pot ie 0.35v and the AFM mixture screw in the right position does seem to cure this problem for a while , but it could still be an air leak,,,sorry to hear that your having a few problems ken , it is a nice car though....
