Any advice please i have been getting an intermitant check engine light causing loss of power engine revs drop to idle then if you try to accelerate it eventually stalls and is then very hard to get started unless left for sometime.this problem is very unprodictable and the truck will run ok for a while and then it just fails. I have checked the obd and it is showing codes 14 and 32 i have reset this and ran until it failed again and it showed codes 14 and 32 again i have checked around the various electrical connections and vacuum hoses and nothing is obvious before the onset of this problem i did have some erratic idling and rev surges this would come and go and would usually last 5 miles and then cure itself i wondered if this was relevant any help would be much appreciated

What engine?

Sounds like a problem with your MAF or VAFM. Have you installed a "cold air intake" system or modified the intake in any way?

thanks for the reply mate the engine is a kzn130 turbo diesel no air intake mods fitted there is one small plastic sensor fitted on the inlet side of the air filter box then the pipe goes directly to the turbo. is this sensor the likely cause of this fault

You're talking outside my area of expertise now. Don't see many TDs in the U.S. I don't know how the MAF/VAFM works with a TD engine. Sorry.

went out again today with the truck for it to fail on me again after 6 miles sudden loss of acceleration revs dropped back it wouldnt rise over 1000rpm tried it whilst stopped the more i tried to rev it the engine check light would come on and then go out when i allowed it to just idle. I shut off the truck and had to wait 10mins until it started and i regained full power which then allowed me to travel home could not create the fault at home whilst parked up.

gotta go with Rabbit on this one, not many TDs here in the states.
I say your truck just likes to embarass you out in public.
