not sure where to post this but is there a way to lower the idle without getting a tune?? i know if i turn the a/c on it idles lower but i dont exactly want to run around with the a/c on all the time. my car idles at like 1100-1200rpms, seems kinda high to me.

 

Prolly gonna need a tune

 

1100-1200 is definetly high.. check around for a vacuum leak after the MAF ... sounds like unmetered air is entering thus raising the idle... either that or if you ever had a tune w/that 224 they site the idle high....

But either way... only right way of doing it is with a tune.. but i'd investigate why the idle is so high before getting a tune...

 

If idle drops w/ A/C on then it's not under IAC
control I expect - either a vacuum leak, or maybe
somebody went and drilled the throttle blade, etc.

 

You could always try backing off your throttle screw. When I was trying to bring my IAC counts down i adjusted the screw too far and the car idled over 1000 rpms because i guess i crossed the idle throttle position threshold. It was even in cell 22 instead of cell 20.

 

thats what i was looking for, how you do this? do i remove the iac and then theres a screw under there or something? not seeing anything anywhere on the tbody to adjust.

 

my car was stock when i bought it a couple months ago its always idled around 1100rpms.

 

It's what the throttle cam rests against when the throttle's closed all the way.

ok i must be retarded then cuz i dont see no screw or anything to adjust on any of those pics or on my car.

 

im assuming i remove the tps sensor and theres something to adjust in there?

 

Idle stop screw is an upside-down Allen head
on the bottom of the TB casting stop boss.

 

hrm, sweeet ill have to look for that then, thanks

 

is that what a scanner says its idling at? It may sound like a dumb question but my stock tach is off by 300rpms at idle. If it says im idling steady at 1150-1200 hptuners is saying im at 950...the reason i say this is the stock settings for an m6 command i think 800rpm idles once your warmed up so if your tach is off like mine it might be correct

 

yup thats very possible, doesnt mean i still dont want it to idle lower, with the a/c on it idles at 1100rpms on my tach and just sounds but with it off it idles 1200 and i loose a lot of the lope.

 

I wouldnt trust the dash guage either. Since you said that it has always idled that high I would check to see if the throttle body blade has been drilled. Then I would check to see if the screws on your intake are loose. I would also check the throttle body screw (turn to left). Last I would check for a leak between the intake and the mass air flow. A tune will not fix any of these things by the way....

 

theres no leaks and everything is tight, i tripple checked everything after the intake install. idle is the same it always was. i havent had a chance to check the stop screw since i was installing my torq arm mount all last night what a pain in the butt!!
