Mine seems high at about 825-850.

I followed the stickie and tried to adjust it, and everytime i get it to about 650, no load in neutral, turn off car, reconnect tps, and start her up, it'll climb to 850 in neutral "or" drive, no load. Any ideas here fellas?

It just seems to be sooooo smooth at about 700, but @ 850 i get a bit of vibration-just seems off 2 me. thanks

cold its around 1200-1300

after warm up around 700

if i drive at 80mph for 20-30 mins str8 on the interstate i get as low as 600 (seems odd)

thefed

700 sounds right. mine is 850 and seems high, and this is at normal operating temp. and evrytime i adjust it to 650 ish, i reconnect the tps and she shoots up! arggghhh

Somewhere in the stickies, it should say to check RPM when the cooling fan isn't going because that puts a load in the system. Also, ensure that the radio, ac/heater, radar detector, etc. is off. It also says that in my Chilton's manual. When the cooling fan kicks in, the RPM should slightly climb. If your reading 850 RPMs when the the cooling fans are going, you should be ok.

about 900 norm,
but depends if u have A/C on,
start up 1,300
but otherwise i only watch it go higher i dont watch it go lower.

im gonna check if the cooling fan is on. i remember seeing that. good point -thanx

Yours is a little too high if you are at 900rpms w/o any accessories turned on. You should be at 750 tops. 95 - 5 speeders should be around 625-650 RPMs, all accessories turned off. I'm usualy at 650 - 675 RPMs, when I use the ac/heater it goes up to 800 RPMs. High idle speed can affect your gas mileage. My car used to idle at 950RPMs before I adjusted it. I noticed a difference in gas consumption.

will check when driving tonight but i think its about that, with subs lights and speakers, not to sure will definetly check

Best time to check is when you get home while engine is still warm. Make sure that the temp gauge is on normal level, it should be just under the mid-point Turn off all your accessories, I mean everything but the engine. Make sure the fan isn't going. If its running wait for it til it stops, shouldn't be long. But make sure you act fast and read the RPM because it can turn back on depending on how hot the engine is especially after driving it from school or anywhere else to your house. Don't step on the brake pedal either.

at warm up, i get 1500-2000 and then it drops to about 850-900 on neutral. i think my idles too high.

Wills98MaxSE

about 700-800rpms in D

so does anyone know why this is happening to me? how can i resolve this (see my 1st post) thanks. btw its an auto if that matters

First of all, post the steps you've taken to adjust your idle speed.

According to the Haynes shop manual:

1995
Manual transaxle 550 - 650
Automatic transaxle 600 - 700

1996 - 1999
Manual transaxle 525 - 625
Automatic transaxle 600 - 700

According to the shop manual this is the correct way to set the engine idle speed. This is done when the engine is at normal operating temperature, in neutral with no loads on. (run for at least 15 min)

Step 1 - Place the ECU in diagnostic mode, Turn the ECU screw clockwise, wait 2 sec, then counter clockwise, wait 2 sec, return to center position, you should get code 0505, if not, repair the problem and try again.

Step 2 - With the system in diagnostic mode start the engine and rev it to 2000 RPMs several times then allow it to return to idle.

Step 3 - If the idle speed is not within specifications adjust the engine idle speed using the idle speed adjustment screw. (Not the throttle body default stop) The idle speed adjustment screw is located on top of the throttle body right next to the IACV. The Haynes manual, section 4-12 has this writeup with pictures.

Step 4 - When the idle speed is correct, simply turn off the engine.
NOTE: This should record the desired idle speed and disable diagnostic mode.

According to the manual, thats how you get the correct idle speed.

okay, heres the deal. i turned off the car afterwarm, unplugged tps, started car, adjusted throttle stop screw til i idled at about 650ish.then, i turned off the car, replugged the tps, and turned it on. idled at 850 no load, in neutral,park and drive!?!?so i repeated process, lowering idle to like 500!, same result, 850 idle. i even fawked with the iacv screw a little, no luck. please help.

ps i even lowered it to the point of stalling, plugged tps, and she goes to 850!?!? wtf?

Was the cooling fan running when you were adjusting the idle speed? That makes a difference. If the fan was running, wait til it stops then adjust some more. During adjustments, absolutely no accessories shall be on, not even exterior lights nor your courtesy lights which means keep all doors closed.

thefed

no man, i mean "no" load. wtf ? i have NOOOO idea?!?! im stumped. it has a mind of its own whith the tps plugged in....

Hmmm...interesting! My Chiltons didn't say about putting the ECU into diag mode. But I was able to adjust the idle speed w/o any issues. I'd say do what njmaxseltd suggests and see what happens. Make sure the ignition switch is turn to ON position (do not start engine). Then simply turn the diag screw on the ECU clockwise til it stops. Wait 2 secs, turn the screw counter-clockwise til it stops. ECU should be in diag mode.

anyone have a picof the "idle speed adjustment screw" up close? is it the black plastic screw? i thought that was the iacv screw? i tried it anyhow using the above method, and nothing happens no matter what way i turn it? do i need to disconnect the tps as well? AHHHHHHHHH!! im goin crazy

such an easy project turned into a 3 hr nightmare! i just want to lower my idle. with no tps, i can do it, when i re-plug it in, it goes to 800-850. any help would be great

hmmm 600 huh. Sometimes mine idles at 450 and my car vibrates a little bit, I already adjusted the Idle screw... I just dont know what to do except clean the IACV

my car idles at 500 in drive, and 700 in neutral....seems fine to me..

DRIFFT MAX

ok ok i checked it after class and the the car on start up no a/c is 700-800 with a/c 1000
in drive like 600. after warmed up it stays the same.

Looking at the photo below, is around the area where the white arrow is. It's a cream colored large plastic screw (philips-type). It's where the TB and IACV meets but it seems like the adjustment screw is on the IACV housing. There's nothing like it around there.

on good days 700-750 bad days 500 . ok days 800 :/

Mine's at just over 600 in drive.

the screw you want to adjust is located in the above pic. On mine, it is a black phillips head plastic screw located on the IACV near the connector for the TPS. There are no other screws near it, so you can't miss it if looking at the top of the IACV. From your posts, it sounds like you've been adjusting the throttle plate stop screw. That would be the wrong one....

I think the reason the ECU needs to be in diagnostic mode is so that it will "learn" from the adjustment. If its not, it may just decide to correct to its preset specs no matter what you adjust it to. I could be wrong on this, though. But I've tried adjusting mine with the right screw but not in diagnostic mode, and it did the same as yours...
