Wonder if anyone can shed light on this:
Petrol or LPG around town: fine on both
LPG on motorway: I put the foot down, and nothing. It judders and seems to gasp for breath. I switch to petrol, then it's OK. Just OK, like a 1.3 shopping trolley, not like a bat out of hell.
There was stuff coming out the exhaust - looks like horse hair, probably sound deadening come apart.
Then back in town, I stall on LPG.
???
-
Then, when I fire it up again on petrol or LPG, blue smoke comes out the exhaust.
-
what engine? 2.0, 2.2, 2.5, 2.6, 3.0, 3.2?
What type of gas system, SGI or mixer?
-
Exhausr internals are coming apart and blocking the exit of gasses.Happened to me on the M11 a couple of years ago and it felt like the car had lost 100bhp.Revs were hunting up/down similar to your description.
You need a new back box (at least) but for the moment,get an old coathanger,bend a hook on the end and fish the rest of the glass fibre out.That should provide a temporary solution and prevent the box from exploding under the pressure. :y

Must try to type faster

2.6 V6 Tartarini multi-point.
I've done the coat hanger thingy but I pulled most of it out already last week.
I'd better go to an exhaust place - don't fancy an explosion while carrying small kids around!
-
Another vote for exhaust internals... Fix that first ;)
-
If the fibreglass had come out, how come the car isn't any noisier?
ebay are doing a german system for £100 (search 'omega 2.6 exhaust') but I'd have to pay £50 for fitting somewhere.
A well-known retailer whose names rhymes with Slick Brit want £140 just for the back box, albeit fitted.

I wouldn't let the well known place work on a wheelbarrow ;) ;)

Try Steve at Heathrow Omega spares.He may have a good used exhaust at a decent price. :y
Other wise Eternal. :y
The back box doesnt make a huge difference to noise level imo.Most of the silencing is done by the centre boxes. ;)
-
WoW! :o I'm in Heathrow area! ;D ;D ;D
I gotta go see this Steve fella.
Will let you know how it made a difference in about 7 days...
-
Not sure on an used exhaust personally, unless its free or cost of a beer, buy new. Its only £120 cat back for brand new V6 zorst from eternal :y
-
I sold one a while back for £40 which had only been on the car for a couple of weeks before I dismantled it. ;)
Depends on the exhaust and the budget imo. :y
-
OK folks, I bought the German one on shebay.
Awaiting delivery, then get it fitted.
Car stalls pretty much every stop light so the sooner it arrives the better.
Will report back...
-
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. :-\
-
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!
:D :D :D

Has somebody got a phone number or link to eternal. Sorry to hijack :y

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?
-

Forgot to mention, the rough running is on both petrol and LPG both.
-
Time to read the codes.
-
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. ;)
-
;D ;D ;D
All fixed.
New airflow meter, new plugs and new leads.
Moves like the proverbial off a shovel (on petrol or LPG)
Fin.

Glad you've finally got it sorted.. ;D
