Unplugged the yellow connector on the AAC today and restarted my car. My idle decided to shoot to around 1500. Am i right in assuming that this is the base idle now as the IAA is getting no commands from the ECU? why the feck would anyone set the idle to 1500 RPM? It's not that it would be hiding any problems as until recently the car has been idling perfectly yet slightly high at 950rpm, before cleaning out the TB's and idle valve in situ it was idling spot on at 750

 

It defiently looks like someone has had this plug off before, so I am assuming it's been adjusted before

 

My TPS voltage is currently reading bang on 0.42 volts. And I have a steady idle of 950rpm when the yellow connector is plugged in.

 

 

any one successfully removed and cleaned the IAA unit?

scrap all that. base idle is set at 750rpm correctly. I'm not sure why i got bizarre readings last night maybe it was down to car cooling down or shit in the iaa,

 

as soon as i reconnect the Idle control connector it goes up to the same old 950rpm, so its defiently something its being told to do. or I have a boost leak? going to try hunting for one of them later.

750rpm? Nah thats what idle should be with ECU control ;) Base idle should be set to between 650 and 700rpm ;)

If your air con is on then the idle will increase to 950 rpm. Switching the rear-window demister on has an effect too, if I remember correctly! Did you check this?

Already checked Rory but good point ;)

thats what i meant :P, but without a conzult it's kinda hard to judge from the in car gauges ;)

"Sorry I was speeding officer.... I don't have my conZult plugged in you see so didn't know what my exact speed was....." :rofl:

 

Mike, there's a big dial on the dashboard that says RPM on it, this tells you what the engine is revving at believe it or not. Another great invention from Nissan... possibly a first :rofl: ;)
