third time in about twelve months, it started snatching when driving in town, 2nd gear, it was like i was stomping on the accelerator, (ive done the fuel bypass) so i had a quick look at the clear pipe ,no air bubbles?? but it was ticking over at about 1050,rpm so i parked it up till swmbo, came out of wilcoes, started her up ,perfect again,, anyone had simmilar probs with a 2.5??

Hi Terry

One posibility if it kangeroo's particularly in first gear then the EGR valve may be stuck. Symptoms vary depending on what position it has stuck in but it can also play havoc with the signals to the ECU which will then compensate by altering the idle setting up a bit. If the valve is only sticking some of the time locked position may vary and any symptons change with it.

egr valve, oops disconnected it last year, did not fancy all the crud building up on my inlet valves? (worn valve stem seals)

Hi Mike

Behind the engine. Noz has posted previously on how to service/blank it off.

I had this problem with my "fly by wire" 2.1td, it was the throttle potentiometer, I think the internal "tracks" get worn in the most used range of movement, I swapped it for another used pot and the problem went away.

Good luck, Colin.P
