Hi all. My idle problem is quite different. It idles high, around 1400 for about 20 minutes then drops back to a nice 900. It always does this, in any conditions. I've had 3 mechanics look at it. I've replaced the idle module, rebuilt the intake manifold and head, cleaned the injectors and serviced the air flow meter. I have the mixture screw all the way in otherwise the startup idle would be around 2000. Any help would be appreciated
