1. Is IAC clean?
I haven't checked, but agree this is a very good idea. Plan to do this when I get around to checking my valve clearances.
2. Have connections to IAC and EOT been disconnected and reconnected to "wipe" the contacts to insure a good connection?
Haven't checked the IACV (will do), but have replaced the EOT sensor, and have had it disconnected and reconnected several times.
3. Plugs read?...burning clean?
Checked them once, the first time the problem surfaced, and they looked perfect.
4. Check for vacuum leak (from post 570: I had a failure to idle issue on my V7II, first experienced at 8,000 feet altitude, ~5 months in service and 6,000 miles. It required throttle to maintain idle, even after returning to 2,200 feet elevation. Cured by tightening band around rubber from single throttle body to intake manifold.) It was a quick restart when it died, also.
Haven't checked, but this is a good suggestion and will do this. Can I get at all four without having to disassembly a whole lot of things - like removing the gas tank?
5. Connections to all other sensors (O2, IAT, CKP) disconnected and reconnected to "wipe" the contacts to insure a good connection? On the XLForum, 07 up Sportsters have solved several issues by cleaning the CKP connection, which is down low and exposed to road grime.
Haven't done this, but will.
6. Sensor values compared to FSM values?
Not yet.
