Engine is 'hesitant'

[bighammerfan]

HI. I now have my car back and on the road after having the timing chain break. It starts up fine and when accelerating its seems fine but when i ease off the accelerator pedal it seems to 'hold back' but not constantly just randomly. It doesnt miss fire. It has had new plugs etc. Any help would be great

Sounds like you're having the same problem as I am am.

Check out my thread:- http://www.vectra-c.com/forum/showthread.php?t=117682

Some people have posted suggestions on there, however, my problem has got worse this morning

HP Fuel pump on its way out maybe ?

Is that an expensive thing to replace Spennny? I sure hope not. Have spent a small fortune on it already this year.

Tell me about it. I have spent £1200 this week on mine !

My bills haven't been that bad but not too far behind.

I just checked on EuroCarParts and the fuel pump alone will cost £387.00.

Spennny - Could this possibly be a loose connector? If so, where do I locate the fuel pump on a 1.9 CDTI 150 so I can check it?

Would a dodgy fuel pump be worse when accelerating though ?

Mate i couldnt tell you where the pump is on a 1.9 CDTI

Yes, cause it has to pump more fuel to the engine ?
