Air Regulator Hole Open Normally?

[starscream_r32]

Hi all,

I did the AAC and Air Reg clean recently and now my car idles higher then before i cleaned them!

It's currently idling at 1100 and sometimes goes up a couple of hundred.

Not sure what the problem could be.

Tried turning the AAC screw but wouldn't bring the revs down and if i turned it down to much the car stalls when engine is cold but when warm it stays alive but idles 1100+

Anyone know if the Air Reg is meant to have a tiny gap/hole when normal? I recall when i assembled it together after cleaning it i looked through the hole/pipe and i noticed it's not fully blocked off and there was a little gap/hole.

If that should be fully closed then that might be why i got high idle?!

Any other suggestions would be great!

Thanks.

You need to disconnect one of the plugs on the AAC valve I'm pretty sure to adjust it

Or maybe one of the TPS plugs?

Sorry don't remember which one. But once you do this your revs will drop so if you've wound it in it might stall.

it's the TPS plug you disconnect. this drops it into base idle mode and you should be able to wind the idle down. if not then you might want to pull the AAC valve out again and clean it again.

i tried pulling tps plug out it took the idle down to 900 but any screw adjustment didn't change the idle.

and when i plugged the tps back in the idle went up again!?

any thoughts!?

thanks!

i had a funny feeling it was the aac plug because if its still plugged in the computer can open or close the AAC valve? But hey it probably is the TPS. It should work if you can get it into base idle mode anyway.... dunno why it wasnt changing the idle

Screw in for revs down and screw out for revs up I think?

Been far to long since ive had to do this lol

Perhaps try resetting the stock ECU if its still the standard one

the idle adjust screw has a small rubber o-ring around the inside. maybe when you put it back together you left the o-ring out? it shouldnt even be removable really, from memory it has a strip in the centre that is threaded thru the middle of the idle screw. but mine had come off when i pulled it apart.

Unplug the AAC when adjusting the AAC idle screw. The air regulator should be fully open when cold and will close as the engine warms up. It should be fully closed when the surrounding temp reaches approx 60degs.

according to the r33 workshop manual you only unplug the AAC valve on a GTR. on rb20 and rb25 powered cars you unplug the TPS.

If it is an R32 with RB20DET the AAC connector should be disconnected which is the same for the R32 RB26DETT. If it is an R33 or R34 RB25 it is the TPS. I double checked with the R32, R33 and R34 workshop manuals.

This sounds about right
