Just change Blue Sensor, Its a quck job to do and dont forget to top up water when u do it. Dependin on how much you loose, and replace seal as well with it.
Jeez, Ive jus realised the heat now, as I sold my Carbon Bonnet, less heat inside at the time, now with the original bonnet and jacket on the inside, more heat cumin through.. A/C run out! 'Mofo'!
MAF or AFM would'nt make that sound like that.. As JP said change the leads is the first option. And having an uncracked coilpack does not necceasarily mean that its not at fault!
