one last question on IDLE CONTROL MODULE
ok so im about to buy a 30 dollar used idle control module. i pulled the one out of my 325e and it was fried, circuit board and capacitors transistors were burnt. (read previous posted threads about how)
so if the idle is "surging right now, from 750 to 1200 or 1300 RPM
and i have pulled the control module, should i be worried about having to replace the ICV as well? im hoping once i get the part that all is cured.
also on the direction of when i replace the unit. should i pull the throttle switch, tune the screw on the ICV and set it to 750 RPM and then reapply the throttle switch??? or should i just keep everything connected.
one last question to pose, the car is never on long enough to get to normal temperature. but i assume the temperature gauge may not be reading correct it stays at top of blue, does the IDLE control module have anything to do with sending data back to the temperature gauge? so that if it is not working nor is the gauge gonna read right? i read that it does take data from the temperature sensor the AFM and all sorts of other sensors.
