hey all. am wondering if anyone can help me?? have been chasing gremlins round my mk2 since i bought it. its always idled really lumpy and constantly cuts when cold. i also suspect it overfuelling and it failed an emissions test. i've had it on the diagnostics and it came up with an error on the lambda sensor. i then bought and fitted a new lambda but still same problems. i've just been looking through other threads at pics of engine bays and after looking at mine, have noticed that my ht leads are folded over about 3 times as they are far too long and i haven't seen this on anyone elses. it almost looks like someone has bought a set of 16v leads in error. might sound a stupid question, but does anyone know if this could be causing all the problems?
