Hi tunnie,thanks for the reply.I asume oil in plugs would mean leaking cover gasgets,but they are not leaking i cheked.How would oil get in the plug wells also would it not missfire all the time mate.Regards Dean :y

Weak dis pack, made worse by rainwater draining from the scuttle :-\
No EML might also mean no/blown bulb :y

Think you are right al about,rain water draining from the scuttle.Part of engin bay wet,EML is lit when ignition is on.Where is dis pack is it easy to replace,shit i am going to birmingham in a few hours. :(

Also check the sponge under the scuttle, see if its wet. Dis pack is bolted to the back to the engine, right up against the bulk head. It's not too bad to change, scuttle and plenum off for easy access. I popped off the fuel injection manifold too as its just couple of mins to do that as well, helps access to I found :y

Driving with a misfire has the potential to wreck the Cats as they don't like un-burned petrol !!

guess that depends on how much petrol gets inside, and what condition the insides are already .. both factors are unknowns IMHO ... certainly I wouldn't want to drive nearly 200 miles with a misfire .. :(

whip plug caps off and get as much oil out as possible-syringe with pipe on does nicely or tissue to soak it out--will help as short term fix

Al just as a matter of fact,how can i tell if its one cylinder or more.Sorry to keep going on but i realy need to make this trip.

Mine has a slight misfire first thing when started up within a couple of miles its fine. I guess that its oil in the plug at the back n/s that seems to be where the oil leaks from the cam cover. last time I took the plenum off I had a good look at the diss pack and it was fine. Oil in the plug well more likely on yours I would say. have look first it would save a bit of unnecessary work.

Have you read the codes?

Thought there was also a guide for resealing the scuttle,but can't find it :-\
A blast of WD40 over the dispack should help with any moisture there. If that doesn't make a temporary difference then you can identify which plug is misfiring by removing/refitting each lead in turn whilst the engine is running. The lead that makes no difference is where the misfire is :y EXTREME care is needed doing this. If you are not properly insulated you will most likely get electrocuted :'(

Well just a quick update.I took the chance and drove to birmingham friday night.We got to our hotel at 3.30am,so as i have AA cover i will give them a call.Wished i had not botherd retards(but thats another story).The mechanic checked all 3 drivers side plugs and leads,but would not check the passenger side.As he said there was to much to strip down,so i refused relay.Did what i had to do sat,and drove back sat afternoon.So no missfire on drivers side,but unknown on the pass side,so tommorow.I am going to sort out new leads,plugs and coil pac/dis pac,then to try to find someone i trust.Up here to fit them,i would like to thank evryone.Who contributed to my thred,its very much apreciated.Regards Dean :y
