I have the same problem with my 406 it has the 2.1 engine. The problem occurs when there is no load on the engine ie running down a hill. The car is fine at other times and if you keep the revs above 2000 there is no problem. the problem seems to be at 1500 revs. I will have to scrap the car if I cannot find a solution. Any ideas?
