engine running like bag of s**t
 

:mad: Hi ive had a 2.0l coupe 02 reg for about 4 weeks now which has been off the road, (acident damaged). It is fully repaired now and ready for an mot but I started her yesterday and its running like cack. it sounds like a V8 ticking over and has no power, engine fault light is on. When I first got the car I think it was running ok but havent really started it since, battery's gone dead a few times and been recharged on the car, could this messing around with the battery damaged a sensor maybe?
Thanks for any help
