Hi I was getting p0505 and p0120 doing a paper clip test on my 1.6 x16szr engined astra. I have replaced the icv motor p0505, and the throttle position sensor p0120, i also cleaned the throttle body and the egr valve.
the problem was fast idle and the eml comes on on idle but not when driving. i cleared the codes but im still getting p0505 and the light is still comming on and its still idling fast.
any ideas what to try next
please help that little light is driving me nuts.
