MISSFIRES

[dave_h]

Hi,

I'm having problems with missfires in the wet weather
I've already replaced HT leads / distributor cap / rotar arm / plugs.

This solved the problem for a while but over the last very wet weekend missfires have started again. It doesn't seem to dry out either - when left overnight or while driving.

I'm tempted to replace the coil today - It's very old
Does anyone have any other ideas as to what to try next??

Cheers

Do you have any kind of splash-gaurd?
proven techniques include...

The ice-cream tub lid: zip tie an ice-cream tub lid behind the grille in front of the dizzy, this will offer protection from puddles etc.

The rubber glove: get a rubber glove, cut off the finger tips, put glove over dizzy and thread the leads through the fingers, tape/zip tie the fingers up, this will waterproof the dizzy + it's connections. Obviously make sure everything is dry before doing this or you will just trap the water in!

Hi Darren,

Yes I do have a splash guard but I will try your suggestion aswell.
Do you think it will definitely be the distributor getting damp as I am driving along??

if it is only doing it in the wet thwn yes try sparing some wd40 on leads and plugs whenthis happens to see if it stops it

I did try spraying the plugs and leads when I was out in the wet but had no joy (they all seem dry anyway).

Through a process of elimination I guess it must be the distributor.
I'll try the rubber glove technique - go out in the wet and see if it stops it.
I'll let you know.

Nice 1

What ignition system are you running - points or electronic? If the spark is breaking down then new parts that werent the cause of the problem (if you see what I mean) would help for a little while. It is worth changing the points and condensor if using that system as they are only a couple of quid, and if it continues then change the coil, they are only 10/15 quid. After that you will of changed all the major electrical bits so it should work fine!

Got some good new leads. I'm not getting shocks of them anymore.
Seems to be firing much better.

Just have to wait for a wet day and see if i still get missfires.
Guess I wont have to wait for too long . . .

Thanks!!:) :)
