Thanks for all the info from the last one! But how do i install? If I go to NAPA will they really have a Stepper Motor, if so is that what it is called there? Oh and the rumble in actually not felt when moving, only when idle. Someone said check plugs or something? How to and what part to replace or clean |

search the archives on this..there is a post that has the part numbers for napa and another big one..i think pep boys..there is also a link in one of the posts showing you how and where oh and its called a stepper motor there..check you spark plug wires and the wire from your ignition coil to the distributor cap as well...you need a repair manual...get a disco/lr one or a haynes manual |

You want a stepper motor from a high performance GM vehicle with the 5.1 l engine. They were found in among others, the IROC Camaros. You will be looking for an Idle Air Control Valve. They might not recognize stepper motor.
Installation is simple. The IAC valve is the thing that is at the very back of your intake plenum on the passenger side with four wires plugged into it. Unclip the wires, unscrew (use big-assed crescent wrench), spray lots of carb cleaner in opening to remove carbon, apply blue loc-tite, screw new one in, reattach wires.
As for other things to check, depending upon the miles on your rig and the past maintenance, you should probably check the plug wires (the plug end is exposed to some extreme conditions), condition of distributor cap (carbon arcing on inside and outside, cracks, etc.) Rotor (be careful in removal it is easy to disconnect the advance springs, requiring complete disassembly of the distributor and removal from engine), and finally, ignition timing.
Any of those out of limits can cause major performance issues.
Peace,

The AC Delco Part Number is #25527077.
The NAPA Part # is MPF31738
Why are you replacing this part? I have just usually cleaned mine with carb cleaner and it has functioned fine.

I have a feeling that there are at least two or three stepper motors. First of all, on post '96 vehicle, the IAC valve is not on the back of the plenum and takes a tiny, 5.5mm nut driver to remove it.... |
