Help!! I'm tearing my hair out to find the reason for my 940 stalling in very hot weather.It happens every summer when the temp gets around 40c. I assume its's caused by vapour locks. If you open the bonnet and let it cool for 15 mins it runs ok for a few kms before it happens again. All other times it runs perfectly. I have "googled " this problem with no real concrete answers. I can only think of getting the fuel pumps replaced to possibly cure this problem, but I would hate to go to that expense and not getting a fix. All ideas welcome!!!!
