Hi Guys, ritght been on a mission today to find out what is actually wrong with car.As recommended i checked the recesses which were all ok as i did blow them out before i drove back from germany. I also took off the coilpack and dismantled it and found slight corrosion which i cleaned but no joy still stuttering!!! So i took it to a local garage where they did a diagnostic on the vehicle and it come back with a fault "IDLE AIR CONTROL VALVE". Now i'm not sure how this works and if i can dismantle this to see inside. So is it possible for me to take this apart so i can clean it or will a new/u
