One of the guys changed the Cam cover Gaskets for me this week when I was away. Got back late friday and started the car up at work to get home. All seemed ok but after about 5 mins she started to run really rough and got worse over the 10 mile trip home. Wouldn't go above 50mph, no guts when I tried to accelerate and she just kept misfiring.
Opened up the bonnet on Saturday morning and checked the HT Leads to ensure they were all seated properly and were all fine. Started her up and she was fine again unitl I took her out on a run and again once she was warmed up she started missing again. I check all the breather pipes all the connectors to ensure they all went back on again after the gasket change.
Don't know what else to try??? Anybody got any ideas??

Can you confirm that the engine light comes on and goes off again when you start the car (just in case the bulb has been removed)...
and is the engine light coming on when the fault occurs...?
-
Yes, as M_DTM suspects, I guess the EML should be coming on, and if you do a paperclip test will get a code 17....
-
There's no fault light on or indication at all from the dash that there is a fault

Does the EML come on with ignition?
-
Yes the EML comes on with the ignition and then goes out when started and stays out. I've let her cool down for the last couple of hours but is still rough now when I start her up

OK, I am guessing that the leads got submerged in oil and plug wells filled up with oil, hence reason gaskets changed?
Check plug wells have no oil in them.
The leads do not like being baked in hot oil, and may have broken down.
-
OK. Sounds like that maybe the problem then. The Plugs were submerged in oil but I managed to get most of that out as best I could but obviously was like that for sometime. Will get new HT Leads and see how I go with that. Cheers

What make of gaskets were used?

Mark , I read in great detail your Technical Post on the changing of the Cam Cover Gaskets and got genuine VX Parts and the Black Goo to do the job. Unfortunately I had to go to Germany at the last minute for a meeting so one of the lads did the change. I had already gone through and removed most of the oil from the Plug Wells. I got in contact with VX this morning for the replacement HT Leads and they wanted to charge me £92 for one bank. I've been in touch with Euro Car Parts and they have quoted me £49 for the whole set. I can't see that there would be a massive difference in performance for the HT Leads??????

Donnow about ECP leads, but the Bosch ones are:

Not sure where you might get them though...
As you can see from the other post it seems that V6 Vectra leads may also be suitable...
-
I went and collected the leads tonight from ECP so will fit them tomorrow afternoon whilst the boss is away and report back.
-
OK, Collected the HT Leads from ECP yesterday and fitted them this lunchtime. Took it for a nice long run on the motorway to get it nice and warm and then did a bit of country lane driving just to make sure that the problem was cured. She ran like a dream. The Leads were £49.68 plus VAT which in total came to £58.37. Part Number 409720141 if anybody else needs them. VX in Aldershot wanted £92 for one bank. Thanks for all the advice. Next it's the gearbox so will back on this weekend for advice no doubt once I have grown somemore skin on my Knuckles

Glad its sorted, and for a decent price too :y
