Hi there,

Last week I drove through a partially flooded road ( was pitch black in country lanes and didn't see the water >.>). I drove on for a bit and then the engine cut out. The 'mechanic' who came out managed to then flood my engine trying to start it

The car was recovered back to my house, managed to get it started the next day however it was misfiring...

Been quite busy so had left it for half of the week, then managed to go in town and went and bought new spark plugs and HT leads. Fitted them both yesterday and the car started first time without misfiring at all.

Took the car for a spin and it all seemed fine. Then when I went to go down to a local supermarket the car started misfiring again and I could barely put my foot down without it jumping and spluttering all over the place.

This has happened a few times, however it only seems to do it when the engine warms up? All of the leads are connected properly and the spark plugs are all in properly too...

I've been told that it could be a hairline crack in the distributor cap or something wrong with the coil pack?

Just wondering if anyone would know what was causing this :/

Cheers

As you say, it could be a crack in the distributor cap which is causing your problem, but it could also be one of the new leads which 'breaks down' from time-to-time, or even ditto new spark plug. You could try swapping them, one at a time for the old ones and see what happens.

It does seem a bit odd that all of this started after passing through the floods but now sometimes it is OK.

When I first started to read your post, I was thinking on the lines of water having entered a cylinder and caused a hydraulic lock, which can bend con-rods, but as I continued to read and found that it sometimes runs as normal, I dismissed this idea.

The quickest, and not too expensive first try might be to fit a new cap and rotor arm and maybe spray some ignition damp-proofing spray around the coil, but don't overdo the spray!

Regards.

Thanks mate :) I have tried taking the spark plugs out and fiddling witht he HT leads but same problem :/ Have taken it to a garage now to let them see what the problem is, fortunately it's the guy who i bought it off who is looking at it!

Many thanks though

Got the car back today, turns out the ignition module was broken and wasn't earthed :S lol

All sorted now though thanks for your help btw
