Hi all, first post, hoping can find some good advice.

Have run a 106 1.5 for 10 years and has run perfectly for all that time ... good MPG, starts in under a second, hot or cold weather, zero smoke and always passes emissions.

But the last couple of weeks, it has started hunting and revs vary up and down. Changed the glow plugs for Beru ones (never been done during those 10 years & 75k) and has improved matters but it has cut out twice in exactly the same place two mornings running ... does 3 miles, stands for 2 mins running when drop the wife off at work, turn the corner and cuts out! ... in exactly the same place to the meter, I kid you not.

I squeezed the duel primer bulb which was soft and after three squeezes it goes hard and then starts first time. Thinking an air leak maybe?

Engine has always had synthetic oil, serviced on the dot and prior to this has been perfect. Oh we had a professionally reconditioned diesel pump when we first bought it so not that. I think there is a fuel pump in the tank from what I have read but don't know much about that, has never been done while we have had it. But can see bubbles on the clear pipe coming out of the diesel pump. Engine has done 230k but really has run a dream until now.

Would appreciate any advice or direction on likely source of problem. Can't see any obvious leaks but the fact that the primer bulb solves the problem causes me to wander about that.

Many thanks in advance
