for about 3 weeks now, my car has been cutting out when i slow down to stop or turn a corner going down a gear, not everytime tho. Anyway no dash lights come on to warn me, the engine managment light comes only when engine cuts out as usually, i dont no much about cars, but i took it to my local garage for a diagnostic test, it came back the EGR valve not working, they said it would cost £220 for a new one + labour, and then it may be something else to go with it, as its close to christmas i cant afford it and the car aint worth spending that much on it, i was reading threw posts and some people said cleaning the EGR valve may solve the problem, but dont no where it is or how you clean it? any ideas
