High Idle Speed

About 2 months ago, i got a new AAC Valve (at 60000 miles)... my old one kept stalling when i came to a light.

Currently, when my car's in neutral i seem to have an unusually high idle speed. Well, now i have time to deal with it so.. :)

My idle speed in neutral is 1100 RPM's... where i hear the usual idle speed is around 800 RPM.

Not to mention, im getting ONLY around low 20 MPG for my fuel economy. Does a high idle speed cause low fuel milage?

***How can i LOWER my idle speed a bit?***

you can adjust the throttle cable, but that's probably not your problem. check out www.se-r.net and in the common problem/fixes section you might be able to find some answers and fixes for your problems

your poor mpg may be due to a bad O2 sensor. have you ever replaced it? how many miles do you have?

It doesn't say anything about lowering idle speed. I check the SE-R forum before i post :)

ABout the O2 sensor, im not sure really. Currently the car has about 70300 miles on it. ... Where is the o2 sensor?

did you check out http://www.se-r.net/engine/adjust_idle.html or http://www.se-r.net/car_info/problems/index.html#Erratic%20Idle%20and%20jumping%20idle
either of these might be able to help, assuming you didn't see these when you checked out se-r.net before posting.

i just realized that i've posted 100 times. i remember when i was just a newbie.

Have you checked that the TPS is adjusted correctly?
Also the idle speed may have been adjusted to compensate for a low idle as the AAC
valve was dying. On the RH side of the engine at the back(behind the inlet manifold)
there is a screw to adjust the idle if you dont know what you are doing dont try to change it.
