I've got a 98 EL Fairmont and i have a sorta clicking noise comming from somewear on my front left hand side (i thing its from the front) It only occurs when im accelerating, and as soon as i let go it stops. When i got the window down and i pass cars i can also hear it quite well.
I suspect it is the CANP (Cannister Purge Solonoid) or Purge Control VSV which is inside the front of the left hand wheel arch below the carbon cannister. It should be suspended in mid air by the hoses from the carbon cannister but if it moves so it is contacting the body work or chassis you will hear it in the cabin as it opens and close s on acceleration.
Nah i really doubt its anything to do with the type of petrol, beacause i ONLY use 98ron high octane petrol and nothing less.
In regards to oil, doubt it also as its just had a service less than 3000kms.
Possibly it could be the CANP, though i havn't got the slightest idea of what it is.
How do i make it stop if it is that??
Just move it so it is again suspended in mid air by the hoses and no longer touching the bodywork. It a silver coloured valve with two wires and two small hoses plugged into it and you will find it just in front of the left front wheel hidden in the cavity just ahead of the wheel arch. I say the odds are about 90:1 it's the CANP.
PS to test if it's the CANP just unplug it from the wiring harness and go for test drive. Occasionally faulty ones get extra noisy even when not making contact with the bodywork;if this proves to be the case just replace it. They are not expensive.
