Picture of stock(?) idle air solenoid:
System had an EVAP purge canister valve (said 'auxiliary air control' earlier) also:
I'm not sure whether this is part of current motronic config or it comes from some jetronic system. Harness was connected however.
options
- leave it out and block its connection from throttle body.
- or you can control it from GenBoard. A purge canister can trap significant amount of gases (useful in the engine, unwanted in the athmosphere unburnt) escaped from the tank on a hot summer day (such as today).
- resistance is 46 ohms. This might be a useful idea, but has low priority at the moment :)
- actually I used the drill in throttle body for [IAT]
