Idle control valve read as part throttle open when engine running?
Okay, just want to find out something as little confused...MY02 so mech throttle cable, set with 2-3mm deflection when throttle closed (ie throttle body definately closed). With ignition on, engine not running, AVCR reads 0%, depress and it reads upto 92%, close and 0% static and doesn't change. Run the engine on the other hand and idle bit jumpy and AVCR is reading .8, .4 even 1-2% without touching the throttle, is this possible from just the ICV?
She needs remap anyway but would like to make sure I dont have faulty ICV or throttle position sensor...

Just noticed my post isn't quite clear...
throttle cable when closed has 2-3 mm deflection so butterfly very much shut every time. Cable even lubricated to make sure.
When ignition on, engine not running AVCR reads constant 0% and then changes readings as touch throttle pedal, as expected. Run can though and idle reads 0.4 0.8 and sometimes 2% even though not touching it...it's very much up and down in revs though...any ideas?
