Engine Performance problem
1999 Dodge Ram 6 cyl Two Wheel Drive Automatic 87000 miles
when started engine will run fine than after about 200 yards of driving and at a standing idle you hear the idle air control motor starting to open and while thats happening the rpms drop and engine runs rough. (Lean) a sniff of carb spray will bring idle up and run fine for about 2 min. Tryed a new idle air control motor, fuel pump, throttle position sensor, lower intake manifold pan (in the valley, bottom side) gasket, setting sync. Signal/dist. Resetting all adaptives with scanner, all didnot fix problem. Please help cause the parts bazooka is real low on ammo!
