Hi everyone i have this in at the moment with intermitent cutting out on the road. in the workshop it run's fine, my scanners don't cover it so i am working only with the scope and emissions tester. after checking everything that i could think i found two things that are out the normal. hydrocarbons are 480 ( a bit smokey)
and the oxygen sensor drops bellow zero volts sometimes and this affects the engine note but after more rev's it stabilises and swiches fine am i right to believe that if the oxygen sensor drops bellow zero is faulty? or could this be the burning oil that's causing it? or anything else? thanks
