Now I have a feeling someone is going to say it's my own fault for taking it there but here goes anyway.

Took the car to Mr Clutch to have a new clutch and thrust bearing fitted(Ex-Police so manual). 4 hours or so later and £525 from my wallet and I pick her up, so far so good.

I get around half miles down the road and the dreaded engine management light comes on and she starts misfiring pretty badly.

Plugged her in and faults say "Multiple Misfires and Misfires on Cylindres 1,3&5.

I have tried a new dis pack and Mr Clutch have taken gearbox off and on again and still car is running the same.

All hoses look connected and there appear to be no unconnected wires.

Car goes into limp mode if driven too long/hard.

My only real option seems to take it to local Vauxhall stealer and leave them with an open cheque.

Can anyone help???

Car is 02 plate 3.2 saloon with 60k on the clock,
Before it went in the engine was sweet.

Error codes. p0300 p0301 p0303 p0305

and have tried different ignition coil pack and no change

Thanks in advance

Robert

Keep an eye on my post couple below yours exactly same problem

[martctb]

Just a thought check the lambor sensor connection on that side  

[Entwood]

Have a damn good look around the back of the engine, especially the injector plugs and other electrical connections ...

I reckon the muppets have either knocked something loose, or not connected back up correctly.

[edmsecurity]

I have changed the coil pack, Changed the Spark Plugs,

Can the lamba sensor cause that problem and also the injector wiring loom. is that the connector comming out of the back of the engine sort of center of the plenum.

They have also had it back for the best part of two days and i think its worse.

agreed ..electrical problem..reconnect the sockets.. and check if any electrical cable is squeezed or cut, and making earth..

[martctb]

The loom for 1-3-5 runs back of the engine into the plastic cable run on the ns before heading to the ECU, the lambor sensor can send false into to the ECU and cause the air/fuel mixture to be wrong on one bank, this problem is a nightmare i have the same problem and if i find my cure i will let you know do the same pse.

[edmsecurity]

could the engine management unit next to the car battery cause these problems. i only ask because when i got the car back when they done the clutch the cover in that compartment was not put on correctly and the battery terminals where loose too.

[edmsecurity]

i have checked the lead from the coil pack which just seems to go behind the engine and into the main wiring loom to the right with no other connectors.

if the lamba sensor had an issue wouldnt a fault light come on and be flagged in the ecu

[cem_devecioglu]

go for a known professional and let him check the cam belt positions

ps: found a similiar case on the net..

[edmsecurity]

I cant see how they could of messed up the cam belt but that did cross my mind. i am trying to get them to pay for it to go to vauxhall as i would hope if anyone could find it it would be them.

I was hoping it would of been sorted by now.

[Kevin Wood]

Whilst a Lambda sensor could easily have been dislodged, I wouldn't expect them to affect the running, at least not until the engine has warmed up a bit. If it misfires straight from cold I would suspect something else.

IIRC, if the coil primaries had been interrupted other codes would be raised. Might be worth checking the multiway connector that feeds the injectors, which is behind the passenger side cylinder head.

If you're close to one of us who has a Tech 2 it would be worth a session to see if something can be gleaned from the live data.

Just noticed that you're not a million miles away from me. Could possibly have a look at it if you like?

[feeutfo]

and me, in slough now! Earlys til 2pm.
Have you tried the pedal trick to confirm?

[edmsecurity]

I have a obdii lead and checked it with vauxcheck software and it just reports P0300, P0301, P0303 P0305

Which is a misfire on cylinders 1 3 5 8-)
