New complete exgaust from Germany £95
Fitting from local geeza £70

Car flies along on petrol or LPG now

Strangely not as rorty as my old2.5 V6, but smooth and creamy.

Yay, feel like driving the length and breadth of the UK now!

New exhaust only runs the engine smoothly when at cold temperature.

When it warms up, eg on motorway, it doesn’t accelerate and judders at 50mph+.
It vibrates and runs roughly, as if on 3 or 4 cylinders. (A V6 shouldn't run so rough.)
Then it loses power. I have to switch it off and wait 10 mins before re-starting


Think it could be a faulty crank sensor?
How many hours labour is that?
And what's involved?

If you have managed to hook the remainder of the wadding out of the exhaust but your still having problems with how its running,I think you may have more than one problem. :-\

Forgot to mention, the rough running is on both petrol and LPG both.

Yep - read the codes,check plug wells for oil - usual Omega stuff. If crank sensor needs changing its a 10 minute job. :y

Hi, i was suffering from the same problems as you until this afternoon. I was running out of ideas, i had done the paper clip test (no codes logged) etc,etc. Then this afternoon the side of the back box in the exhaust blew out with the loudest bang you've ever heard, I wouldn't have believed it possible for this to happen, but it has, and now the car goes like a rocket with none of the power loss or hesitancy that i was experiencing before....sounds a bit to sporty for me now though,,,lol  :y

Dave, it can't be my back box, mine's brand new now.

Here's an eternal question: is it worth paying a Vauxhall main dealer to investigate and/or then fix a ten-year old car?

And if not, does anyone know an independant specialist near Heathrow?

No, they are invariably useless.More worthwhile to take a trip to either Alton to see Kevin Wood, or Brackley to see The Boy. ;)

All fixed.

New airflow meter, new plugs and new leads.

Moves like the proverbial off a shovel (on petrol or LPG)

Fin.
