bradc, easy with the hammer, AAR may not get power or?
Try this easy DIY AAR check hot and cold:

Check the AAR located on the right side of the engine between 5-6 intake runner.
It's the item that has a small electric plug and a large vacuum hose connected to it.
Open the clamp holding the outside-hose.
Pry it off with the screwdriver just enough to get it out of the way so you can see into the opening.
Don’t worry about the Alu pipe; it’ll move enough.
With the help of a small mirror and a light, peek inside the AAR.
When COLD, you should see an opening in the slide shaped like a half-moon.
Re-connect the hose, start the engine and let it get real hot.
Stop engine, remove the vac hose again, check the opening again.
When HOT, the opening should be completely closed.
If it isn't closed, the AAR is either kaput, out of adjustment or doesn't get any power.
You can spray some WD-40 into the valve in case it is just sticky.
To check the power, carefully open the tiny clip on the plug with a very small screwdriver and pull it off.
The wire clip is tricky but necessary; don't yank it off.
Start the engine and check the plug for 12 V. (Careful of the fan/belt!)
Just ignition ON will not get power to AAR or WUR; engine has to run.
(One wire is power, the other (brown) is ground)
With power to the AAR, it should close after about 5 minutes.
If all is well, replace the hose and clamp securely.
Let us know if the AAR works HOT and COLD.
