On a 1997 Ford Explorer 4.0 the lean banks 1 & 2 run really rough. This is only when it is cold outside. It runs rough for a few seconds and then runs fine when it warms up. What do you recommend to fix this.....

Test the engine coolant temperature sensor and clean out the idle air control valve and see what happens
