General Uno doesn't like puddles

[john2443]

My 999 injection runs beautifully most of the time, but if i drive through a puddle, somethihng is getting sprayed, and then it fells like it's only running on 3 cylinders.

On a steady throttle it just gets slower and eventually dies, if I push the accelerator up and down it keeps going.

Today was it's worst due to flooding, and it dies completly, I could just get it started but there was no power - as soon as I lifted the clutch the revs just dropped til it stalled. Managed to limp in to work, so am hoping once it's stood for a while to dry out it'll be OK.

Presumably it's electrics getting wet but if anyone has an more specific suggestion about which bit that would be helpful.

Thanks

sounds like the dizzy cap or ht leads spray them with wd40 (inside the cap as well ) and wrap a plastic bag around the cap and secure it, make sure all the leads wires are secure, i emptied half a can on my engine last week (keep out the damp) have a go Ant!

Tell me about it, this is the biggest problem with the rally car !! Will post some ideas when i get from my next meeting.

Right back fro the meeting now.

The FIRE engine suffers from two main things :-

1.) The spark plugs are deep set in the head
2.) With the cross-flow design it means that the inlet side doesn't get hot enough to boil away any water.

The main thing is the deep set spark plugs, this means that water can collect in the spark plug wells this then creaps up the HT lead and then the spark goes straight to earth via the water rather than the spark plug.

Ways round this a few ideas i have found that can work.

You need to keep the water out of all HT leads / wires

Few tricks, fill up the spark wells with the HT leads on with bubble wrap or plastic (over 18 months of rallying hasn't melted any yet !).
Also use WD-40 & or Silicon spray on the HT leads before fitting them.
Then cover the HT leads with more layers of plastic, so as to stop the water ever gettin anywhere near the HT leads.
Then get some silicon sealant, and cover the coil and dizzy with the sealant to stop the water getting in. Also seal around the ignition module as water can get into there as well.

This may be a little over the top, but in general it works

Thanks, I'll give some of that a go, also on rainy days I think I'll go for the queues on the M25 rather than the floods on the back road!

Anyway, having struggled in to the carpark at 9 this morning I was relieved to find when I moved it out of the reserved space an hour later it started fine having dried out. So my free-from-freecycle-with-a-broken-engine-mount-Uno is now parked where it should be; next to a Porsche 911



Thanks
