J30 engine idle control valve

[Jamesa434]

Could someone please tell me where I can locate the engine idle control valve on a 1997 J30 engine? Is it hard to replaced.

Thanks,James

On the Q45 it's mounted on the rear of the intake manifold (plenum) close to the firewall. I would imagine on the J30 it's also mounted on the plenum. It should be only 2 or 3 bolts and a couple of hose clamps to get it out. It could be a PITA resetting the idle if you're replacing it. Don't mess with any of the adjustment screws if you're only removing it for a cleaning or you will have idle problems.

In case I'm wrong here's a link to a free download of the Factory Service Manual. It's a compressed file so you'll need Winrar or equivalent to unzip it. It should have step-by-step instructions for removal and adjustment of the IAC. Good luck.
