Hi all..I experienced this problem yesterday as i was driving home from work. It was on a rainy day. My M40 happens to fuel cut after 4k rpm...even when i rev when idling. What seems to be the problem ? Budden today it was acting normal again...lol...any inputs on this matter? Would appreciate any =)

any sensor wet/kena air, starter sensor? crank sensor ker?

hm..not too sure..went through a quite a few puddles..could it just be because its wet ? cos its all back to normal today..hehe.

there is some symptoms way back. friend when for car wash, car cannot start... crank got but doesn't run. ended up tow the car to workshop. they check suspected fuel pump, get brand new cost around 700+, still cannot start, in the end crank sensor which cost him RM25 hehehehehe.. ham kan!!!!

So, if free just check... maybe sensor expose kerrr

oic..thanks for the input. will get it checked if the problem persist.
