Replaced IAC with a used unit that was clean inside as the one removed.

All three IACs I have on hand are used and present the same resistance using the aged Radio Snack DMM (I want my analogue Simpson multimeter back.) Something like 36-45K Ω. I'm unsure.

The IAC I removed was unable to maintain idle as the engine warmed. It has been a little fussy for some years.

So I imagine an issue with the solenoid electro-magnet.

The 6-year old TPS was fine yet I readjusted it, linkage was fine and I re-lubed the socket ends, TB valve (bushings) are fine, as are grounds and harness connections. Yet the replaced IAC restores a rock solid idle better than before.



Happy Hollow-Dayze.

Wish me luck for a return to the cGMP on contract or the Weirded Minerals / Caustic Chemicals heavy industry pumps and gates. Or maybe heavy media publication press systems. The Winterview fray. With dreams of mighty Finland. A real Republic. And Switzerland also. All feature heavy CAD use (SolidWorks and AutoCAD and other CAD and schematic / power / data diagrams for use in documentation. Online and in print.

Hope that help kats. 1990 240 L'il Red Wagon needs new tires, rear flex brake lines, a cylinder head gasket replacement (as does the verdigris 1992 240 GL), and more. With K-cam hopes for both? Restore A/C in slovenly humid Saint Louis featuring the Oak and Elm Tree Jungle. Canopy cover is nothing what it was in the 1970s, tho.

This message brought to you by Volvo 240. With care, outlasting them all, no mater the clear coat failure! Ha!
