Still playing around with Data scan lol.

 

After the car is warmed up my AAC valve is operating at around 20-22, the car idles at 730ish, the TPS reports 0.42.

 

From reading other threads once warm the AAC should read 15?

 

It's ok most of the time but from cold it can idle sometimes at 1600 ish which I think is high, but then comes down as it warms.

 

Occasionally it also does a bit of hunting, or if you come to a junction and stop the revs stick at around 11-1200 for 5-10 seconds before coming back down again.

 

I've came across loads of threads regarding adjusting idle but they all give conflicting information.

 

From the experienced people what is the best way to get the idle set correctly?

it's a long process...

 

first you must make sure everything is giving the correct readings, the easiest way to ensure that is to make sure all connectors are clean and on correctly.

id still not right there could be either sensor or unit issues. (CAS, PTU, coil packs, injectors .. blah.. blah)

 

fuel filter & plug could also do with replacement (you really want the least amount of possible fault variables).

 

make sure the timing is right (this is critical) and has to be done with a timing light.. so a search on the 6Ps or adjusting the timing.

 

once they are correct and all is right then you can adjust the idle valve.

 

 

I hope that helps..
