ello, my car has been in the garage for nearly 3 months now, and nationwide autocentres STILL cant fix the misfire, its had new pistons, new injectors, and loads of other stuff done. now i am being told need a recon engine????
does this seem right to you all out there?
Does anyone know of anywhere where i can get a recon engine fitted, and what sort of cost i am looking at?
I have a 2000 w reg 3.0 elite.
ps i am in hounslow in west london
-
that sounds rather drastic for a missfire :-?
-
I take it that before they started messing around with it they checked the plugs, plug leads and diss pack?
-
I have to ask this ? have you had the leads and dis pack checked or changed and what about the rpm sensor or the cam sensor. if you have a missfire it is unlikly to be an engine fault but more of an electrical ie ht fault. :-?

What's been done/changed? As Loo-Knee says a bit drastic for a miss fire. I think the firts thing I'd change is my garage! ;D ;D
-
i have had the dis pack changed, the rocker cover gasket, all the plugs and leads, its had new injectors, valves, 2 pistons and the misfire is still there.
My car is in nationwide autocentres, and they just cannot seem to fix it, after all they have done it still runs very lumpy at idle, and now they say i need a new engine so i am at my witts end with it all lol
-
Sounds like they don't know what they're doing!
If they've come to the conclusion that it needs a new engine surely they must have arrived at this conclusion through some process of elimination and, assuming they have changed the pistons, they have already stripped the engine down and rebuilt it so if there's a serious engine problem which warrants its replacement why didn't they spot it and rectify it when they had it apart?
That and the fact that they have also changed the injectors makes me think they are changing parts in a pretty haphazard fashion. I'm guessing they've now run out of ideas an have decided it needs a new engine in the hope that the cost will put you off having any more work done!
I'd ask for it back, avoid paying for anything you don't have to on the grounds that they didn't fix it and start the troubleshooting again, based on the help available on this site.

Have they checked or cleaned the breathers or cleaned the icv. this will cause lumpy idle or it could be a bad fuel filter/air filter.
-
Just noticed your sign in.
Is this mis-fire on petrol or LPG?
-
What sort of milage has it done and has the cam belt ever snapped?
-
Come to think of it, they have had the heads off and i hope they have replaced the cam belt kit, Have they timed it correctly. if not that will cause lumpy idle. they have replaced valves WHY? were they bent ,if not then they could have lapped them in again, if they were bent then the timing may have slipped a few teeth. you need to ask some ?'s mate.

when it went into this garage at 1st they blamed the LPG i had fitted, when they took the engine apart they said there was debris in the chamber which they said came from the LPG installation (surprise surprise)
They did that and i had a tech 2 test done and it said that cylinder 6 was not getting any fuel, so they say they have rectified that and this was after they had changed the dis pack and the plugs and HT leads.
When i went to the garage to collect it when they said it was ready, it was still misfiring, they had managed to get the accellerator pedal loose, and they have damaged my bumper.
They have also ripped out my LPG installation.
After much shouting at the area manager, they have promised to get the LPG re-installed from a 3rd party and to fix the damaged pedal and the bumper.
Now they say i need a recon engine, which to be honest i agree with your posts and it seems very drastic seeing as they have pulled the engine apart several times.
Does anyone have any advice on what i can do legally? or can someone reccomend a garage in the london area where i can take my car?
-
it was running fine in both lpg and petrol, but then one day it just started running very lumpy on idle.
Then once i took it to this garage all these problems started.
They said they replaced the cambelt as well
its done 67000 miles and its had the cambelt replaced before i got it
i am not sure if they have checked the brethers or the icv
-
First get the car out of there and dont pay for any thing that you did not agree to. then go to trading stds and make a complaint as to there working practices, then complain to their head office.If they have fitted parts and have not cured the problen then i dont see that you are entittled to pay for them. As for debre in the cylinder then have they told you what it was, ie metal, if so it would have scored the bores and you will be down on compresion on those cylinders
-
Do they have gen vx tec2? was it just the belt, is it timed up correctly.
-
i had a tech 2 test done at a vauxhall dealer, my friend is a mechanic there, i dont know weather they just replaced the cambelt or the tensioners as well
-
At 67000 miles something catastrophic would have to have happened to the engine for it to be an internal problem. That engine is barely run in and they want to fit a reconditioned one?
I would get trading standards involved and maybe get an independant inspection made on the car and the work they have carried out as it sounds like they have been blundering about in the dark, and, are presumably hoping to present you with a huge bill for their efforts.

ben, have they got a gen vx tech 2 , if not then i doubt that they would be able to diagnois fuel probs to one cylinder without it. 67000 is barely run in

Back in 2002, I had a 3.0 V6 on a M plate.
Stealers got over £1k from me pis5ing about here and there trying to identify the mis-fire.
They assured me that they'd done everything INCLUDING the leads.
As I understood it, they didn't change the leads but merely checked them, one by one - eliminating them as the problem.
Now, at £1k, I had a huge 'chat' with the service manager - explaining that the fault was going to be corrected without further expense from my pocket.
They replaced the leads and problem gone! I'm no expert in cars, just in advising that Stealers are crap too! I hope your solution is as easy now you're somewhere where that I was. Good luck!!
-
Sounds a bit like a fault I had ... pulled my hair out a million times.... turned out to be the HT leads on the wrong plugs...No really it is easily done as the dispack numbering doesn't run in order all the way through ... so you put the leads on (and it is difficulkt to see the numbering when the dispack is in position) think you have got it right and assume that it goes 135 246 on the dispak... it doesn't... eventually it blew the CAT,... might be wrorth checking with a torch
Just checked the Dispak ... it goes 135 462 ....easy to get caught out
-
Having said all that and re - reading the thread ... For me, it is a nailed on dispak failure ... are you sure they changed it?......did they give you the old part ..did you see them change it?.........
When mine went it was exactly as you said ... going down the road and just started running lumpy...
My advice - make sure they have changed it and if they have, the old problem ( the dead dispak ) is now gone so it can only be the leads in the wrong order...cos it is V6 it fooled me I thought the misfire would be more pronounced but it was just lumpy.....
Yes Definately get all the leads off and put them back one at a time ....
-
You cant detect fueling on this engine with Tech2.....you can only see an open circuit or short circuit injector and when its open circuit this has always been down to an idiot removing the injector connectors to extract the inlet and not re-fitting them properly in my experience.
Is the fault light on?
If not, it must be ignition.
As said, it needs the leads cehcking adn they must be connected to the correct turrets on the dis pack.
If they were any good, they would have used the diag tool to test the leads using a test plug.....
-
with tech2 you can cut cylinders out 1 at a time, it turns off the injectors for a couple of seconds. can then easily see if its just 1 cylinder gone down or if leads crossed over probably 2

Whats the update on this thread pls, gotta know! :-?
