How do you adjust IAC screws?
How do I adjust my idle? Turn the idle screw, now exposed from the protective rubber coating, in order to adjust the idle. Loosen the screw in a counter-clockwise fashion to increase idle speed or tighten it in a clockwise manner in order to decrease the idle speed. Ideally, you will want the idle to rest at 650 RPM.
How to adjust idle speed on Jaguar XJ6 SIII?
Everyone who tried to adjust the idle speed on a XJ6 SIII knows that it’s rather difficult to get at the adjuster screw because the air flow meter is in the way. If you take the air flow meter out, you can reach the adjuster but the engine doesn’t run, so no idle adjustment can be carried out.
How did I get the AAV out of my Jaguar XJS?
So the only option was to dismantle the AAV, following the guidelines: Making a small cut to losen up the inner valve holder. The valve itself was severely stuck. I had to jam it out with a hammer!
Where is the speed adjustment on a Jaguar?
It’s an aluminum casting with some hoses going hither and thither. The adjustment is made by turning the allen-head screw (5/16″ ?)which is located in the upper area of the block and a bit tricky to access (doesn’t matter if you’re blind or not—-it’s mostly done by feel).
What kind of allen key is idle speed adjuster?
The adjustment screw can be turned with a 7/32 allen key. My idea was to cut a piece of such an allen key, long enough that it protrudes the hole where the adjuster screw sits in (by 7mm approx). After removal of the air flow meter I glued it in place in the adjuster screw with a little epoxy (careful, do not lock the screw!).

What should my IAC be at idle?
The typical consumer car will idle somewhere in the range of 500-1000 RPM, depending on the vehicle. Consult your owner’s manual to find your specific car’s normal speed. High-strung performance cars may have higher idles, and motorcycles have idles that range between 2,500-4,000 RPM.
How to clean the IAC in a Subaru?

How to fix idle air control in Subaru Impreza?
Once it is out, you give it a good spray with contact cleaner to get all the built up gunk off then also spray a heap down inside the hole where the sensor sits inside the Throttle Body. Then its just a case of putting it back together and starting the engine.
Which is the idle air control solenoid valve?
See below. What Is The IACV? The IACV is the “Idle Air Control Valve,” or more fully, the “Idle Air Control Solenoid Valve.” The IACV directly affects idle conditions, RPM in particular. On cold starts, the IACV sends rpm’s higher than on a warm start. Irregular idle conditions may be the result of a dirty IACV sensor.
What’s the ECU on a Subaru Impreza?
I’ll give the IAC a good clean and reset the ecu on the weekend and then see what if it happens again. Other than this one spot on the hill, the car runs pretty much normal but on the odd occasion if i push the clutch in, the revs drop down to 500 and threaten to stall before bouncing back to 850.
