PMI said:Assuming everything is working correctly, including the TPS, IAC valve, engine temp sensor, etc, warm idle is set at 900+/-50 rpm.
I learned a few new acronyms yeaterday (TPS.....) but I am not sure what IAC is.
I planned a whole weekend of wrenching on my 900, Serp Belt and Pulley, Oill/Tranny flush, Collant level sensor, and now I want to try to see whats up with my idle.

The same for me and this, TTBOMK(to the best of my knowledge), cannot be adjusted as it is set by the ECU.wingnut said:I just bought a '97 900S (2.3L Auto).
It normally Idles at 1000 RPMs
Someone mentioned that was fine, but I thought I'd see what everyone else was doing as it seems high to me.
Any way to adjust it?
