Hi All
Im trying to identify and cure a misfire I encounter most obviously whilst cruising. It was previously an occasional miss, but seems to have become more frequent. Car pulls great when accelerating, but seems to stutter with light or constant throttle application. I think it’s killed my cat too as i needed a favour to get through the last MOT.
Research suggests these symptoms can occur with failing COPs(Im running the standard items), MAF and Temp thermister.
Is there any way of testing these items other than to replace them? In particularly the coils are expensive and as my car only has 35k on the clock, there is probably a lot of life left in whichever components arent failing. spark plugs and leads are presumed to be good as they’ve <5k miles on them.
Many thanks
Ben
