Ah right I understand that Chris thanks. sorry about all the questions guys this is all new to me. I have used the search function a lot today and have already ordered a new coolant temperature sensor, found out its location and how to fit it and how to clean the MAF sensor. Just want to get the car right as its a nice drive and doing the miles I do for work I need to have confidence in it. is there anything else you guys would recommend I had cleaned / changed apart from plugs,oil, oil filter, fuel filter and air filter?
