ANy difference between starting from cold or when hot? I can provoke this problem on mine because I have tricked the coolant temperature sensor with a switcheable control and falsely sending high temp reading to computer when in fact the engine is cold does mimick your problem. But when the engine is actually warmed up, I cannot reproduce the condition...so just for a try, I'd suggest you DISCONNECT the temperature sender: this is equivalent to a low temp reading and will command for a richer fuel mixture...just see what it does. In addition to the AIR temperature sender, here are 2 ENGINE temperature senders: one for the gauge (1 wire) and 1 for the computer (2 wires): I 'll check for its exact location and come back with that info.
