Hi, Ive had this idle problem and posted before and have not really gotta a fix for it and i still cant find whats wrong. When i start my car it idles very high, around 1500-2000 rpm. Once i drive my car for an hour or so and its warmed up and i shut my car off for like 30 mins and restart it again it idles normally around 800. Once i go drive it for alittle bit or rev it the idle jumps back up to 1500-2000. I have a 88 t2. Have anyone seen this problem? does anyone know which pin on the ecu is for the o2 sensor?
