how can i stop my 22re from high idling when its cold. my truck high idles when its cold and surges in between cold and hot and it dosent know what to do. after its warmed up everything functions properly and idles at about 900 RPM which is fine by me. but the engine is old 400,000 grueling miles on the engine and it makes noises at this high idle when its cold and i know its not good for it to be doing this. after warmed up the noises go away. and at a low idle when its cold there not heard as easily. so i just want my idle to be low all the time.
