Long distance journey today, in the wet. Accelerating hard off slip-road when at 80mph and about 5k it felt like I hit the rev limiter...hard!.

 

Then for the remaining 30mins motorway driving at a steady 70mph every few minutes it did the same...a hard jolt, like engine cut out, complete loss of power for a second then it will carry driving on again. Occasionaly it would do it repeateadly for a few seconds as if I had run out of fuel.

 

Had only just put £20 in it and was on a 1/4, but I Stopped at services and put some more petrol in and it would'nt idle, cut out, had to rev it to start it and keep it running.

 

20mins down the motorway later it stopped doing it.

 

PTU failure, Wet MAF/Apexi Filter.....a really had batch of fuel ?

 

:confused:

sounds like wet on the maf to me thats exactly what mine did when the apexi got wet would not tick over had to keep reving the engine to keep it running on tickover

im having same problem but mine wont start, turns over fine,deffo not maf so either bad fuel or dead ptu, if it was a ptu atleast it should have no problem starting from cold shouldn't it ??

PTU gone, they can go intermitent then pack up completley

ptu failure can be complete failure or when it gets hot it will fail,always worth cleaning the ptu connections,and injector connections if the problem still arrises swap for new series 2 ptu

fuel controller unit could be aswell thats how mine started

Next time it cuts out - make a note to listen if the secondary electric fan has come on - if it is then it's a dodgy temp sensor connector.
