Cheers for that ej88, that was my understanding too.
Ok well this is what happened yesterday, as posted on itr-dc2 forums
_____________________________________________________________
Right it all appeared rosy, I drove to a friends after fitting the dizzy cap and rotor arm, and cleaning the plugs, but it still didn't feel 100% right, was odd, but engine light had gone.
Then went to get in it to come home tonight, got to the end of his road, and it started hesitating and juddering again, but this time I saw a flicker of the battery light... aha ... then the engine light came on, turned right back to my friends house and popped the hood.
Checked for error codes and still nothing came up!
But sure enough I could smell that same burning smell I've smelt the whole time, I got a torch and checked the battery, looked ok to begin with, then shone the torch down the side of it, and there was all this white stuff coming out of it, and had obviously been coming out for a while as its stripped the battery holder of its paint.
Leaking battery acid.... I think I may have found my culprit.
Sadly had to leave my car at a friends house, but hopefully Honda will have a battery in stock tomorrow I can take over there.
I actually can't believe I've only seen this now, I really hope its whats causing this problem, as there still no bloudy engine codes being stored on the ECU.
Will let you know how I get on with this.
oh and on a positive note... ABS is working again was water ingress on the relay, all sorted now

Ok well got a brand new battery from Honda (for reference they are the same price as one from Halfords), £63 and apparently always in stock at dealers due to the new Civic using the same battery.
And well the car is behaving as it should, drove beautifully, and hasn't missed a beat since.
fingers crossed this is what was the issue
