C20let is ticking over fine on cold start for 2/3 mins then starts idling up/down maybe round 800-1200 rpm constantly, wideband is up and down 13.5-15.8 ish, when on choke it just sits at 14.2, Iv ordered a new icv, and been checking the maf, seem to be getting 2.4v on tickover which seems to be abit high as most other Mafs Iv read on Internet are 0.9 on tickover, anyone no what volts it should be showing
