coil?

[TVRED]

Hi fellas can anybody help please? My s6 has been valeted yesterday and i think he has got water in the coil as the car is not firing all its cylinders and is stuttering low down tried taking it for a drive for about a hour and a half and still no good my indie fella cant do anything for 2weeks.

can a local garage do this is it a big job ?

or is it best to wait my bloke says you can still drive it but it back fires alot and does not drive very well any advice please.

Leave it in a garage or out in the sun for a day or two and then try it again. Should have dried out by then. Don't drive it too far if it doesn't sort itself though. I made the mistake of driving too far with some dodgy HT leads and ruined both cats......oh well. Good excuse for a de-cat

Wait until night time, start it up with the bonnet open and see if any sparks are visible. If so, that tells you where you have a break in the HT insulation and the corresponding component will need to be replaced.

If that doesn't do it then spray WD40 (water dispersant) over all the electrics and sensors, disconnect every connector you can see (one at a time to make sure they all go back in the right place) and spray the insides, give every wire you can see a good dose, basically get this stuff everywhere.

(You'll probably get some on the exhaust while you're at it so it'll wiff for a couple of minutes when you fire it up, but don't let that bother you.) Next, get a spare set of plugs and change them. (If you've had an ignition fault then you will almost certainly have fouled the plugs by now.)

Have had the plugs replaced and coil WD40 and now back firing on all cylinders phew...........
