Look on ebay there maybe something there or look it up in the FSM if the level stays steady then just plug a resistor in.
yeah..i drove it around alot today..then got home and the idle leveled out..
turns out that the heat from the manfold sent the 'right signal' to the egr temp sensor thingy..
so i am guessing that the heat caused electrical resistance in the sensor thus making it read 'correctly'
so maybe ill just go to radio shack and get a resistor..
but egr simulator?..they seem to only makes those for 5.0 stangs..rofl
the idle is bumped up to like 1100 rpm when i turn on the a/c..and that seems normal..so i am guessing that the ecu sends a signal that overrides throttle control from the egr
steve..turning on the a/c is the only way i know to bump up the idle
i did adjust the wire on the throttle body..but then it just goes back down by itself as if its computer controlled
