Engine overheaded and now it runs funny.

[Si.]

On my way home from work yesterday I split a radiator hose. I pulled over in a HUGE cloud of steam and coolant. I was stopped in a awkward spot fo rlet it cool a little then drove it a few hundred yards to where I could pull over (carefaully watching the temp gauge). Anyway, RAC man came, patched hose and I got home ok, however all the way home the engine was acting really bad, jumpy like it was misfiring. I checked the engine bay when i got home and obviously everything was dripping in water and coolant, battery, electrics, everything so i thought that was probably the cause and would be fine in the morning when it all dried out

So today I drive it to the garage to get the hose replaced (or ordered, didn't have the part in stock until Monday) and the car is doing the same thing. It seems Ok once I get the revs up to say 2000, but when pulling away or changing gear it's jerky.

Any ideas? Has the overheat broke something or do I just need to wait longer for it all to dry out?

It's a Ford Focus.

I was thinking the same myself, re-checked the engine bay earlier today and some of it is still soaking (I'm obviously not driving it until I can get a proper replacement hose on monday)

Will it dry out it's self? or do I need to start stripping things down.. It's not a new car (done 135,000 miles) so don't want to spend an cash on it if possible.

Well, fitted the new hose last night and no leaks or anything, however it's still juddering/missing at times. I've checked the HT leads and they seem nice and dry. It seems to be ok on a nice flat steady road, but as the engine gets more under stress (accelerating, or going up hills) it gets worse.

I've not had the plugs out (don't have the tools for it) so not sur eif there is water there.

Any more ideas what the problem is? am I looking at a big bill?

Gulp...

So damage could be worse than I thought..

When the hose first went it's idle was juddery, it's not bad now but still hickups once in a while

After some goggling I think the coil (as people have suggested) is the next thing to check. Being non mechanical, how easy are these to remove and check?

Has the Oil cap off on Sunday, all was nice and clean, but not checked it since, will do that tonight.

I think off to the garage it will be to get it checked over.
