Had a few problems after a 3 hour drive to inverness at the weekend the car was running fine before. On start up the knock levels can read as high as 70, then drop to 0 then back to 70, but as soon as i pull away under load the knock levels drop normally back to zero or max 15 depending on how hot it is outside, but always drops to zero when driving hard.
Any idea's whats causing this or could it just be a faulty sensor, also at what knock level is it worth worrying about.
Also the car used to idle smoothly between 1300 - 1500, but now idles about 900, which would be ok but it sounds quite lumpy.
Any help appreciated
