I'm going to look at a type r ep3 tomorrow, however it has the electrical fault listed in the title.
The alarm doesn't go off when the bonnet is cocked open from the car, but only when it is actually lifted up.
The current owner says this is what happened:
"Sorry I locked it...
I brought a 2004 Civic EP2 it’s been great until a few days ago..
When accelerating it lags.. it sort of feels like the tyres are spinning but they’re not.
Anyways, it’s been doing this for a little while and I didn’t think much of it until it did it when I accelerated and it almost cut out...
