Hey guys!
i posted here before that my car idles to high. then i was advised to clean TB, check TPS and IACV. did it all, even put new TB with TPS.
and here is what happens: as it says in a manual when u adjust idle u have to dissconect TPS, then adjust screw on iacv and connect back TPS. when i disconnect TPS i adjust screw and car idles perfectly at 650 and then when i connect back TPS it jumps back to 900.....
anybody had problem like this?

 

What's wrong with 900? Isn't that what it's supposed to idle at?
If you don't like it just turn the screw back slightly until its 800. No biggy.

 

Normal idle is around 650, that's wierd, I have the same problem, but mine idles at 1500 on park or neutral!

 

1500? Cold starting idle RPMs. Assuming if it does those RPMs at idle when hot, my first suspect would be the ECT sensor or connections. Check for ECT code(s).

 

where is ECT sensor?

 

and what is it? Coolant temp? Yeah 1500rpms while engine is warmed up.

 

mine idles @ 800rpms cold or hot

 

Mine idles around 700 hot, and 1000 cold.

 

seems like nobody have problem like me

 

my engine idle's at 600-650 but once i put on my a/c it idles at 900. idk if that's normal but i'm a complete noob so it doesn't matter lol

 

Sounds about right.

 

mine used to do that, after about 5 bottles of a 125 shot, my car idles at 900 with or w/o AC on, doesn't bother me...

 

that is f up that car idles high because it put too much load on transmission, thats why i trying to fix mine

 

so normally where is the idle suppose to sit at cold start? and when you are in drive at the stop sign. where is that screw located at.

 

mine idles @900 (cold) 650 when warmd

 

my car use to idle at 2000x......I fixed that problem though

 

what was it?^^

 

idle was set too high. turned it down, with a screw driver. My throttle body sensor, is damaged though..I must get a new one.

 

sounds like a faulty TPS. check resistence on it from fully closed to fully open, it should rise steady, with no sharp jumps. google or even the faqs will tell you the resistence it should be at idle, and WOT

 

my car idles at 2,000 is that bad? on cold days almost 3,000

 

ARE U F***ING SERIOUS......????

 

no i swear it idles at 2K, how do i get that fixed.

 

According to the FSM

M/T: 575 +- 50 rpm
A/T: 650 +- 50rpm ; 700 +-50 rpm in Neutral

 

Maybe your throttle cables are too tight. Do you have any codes?

 

how do u adjust it????????? where is it? any pics?

 

Mine is set @ 650. Had the cables inspected and tightened and still good to go.

 

idle adjusting screw? where is it for the 2nd time??????????????????

 

www.autozone.com has basic instructions on how to adjust the idle, and suggested idle speed. Look under

I have a similar problem, my idle jumps when using the climate control which is expect but when I turn it off, the idle remains almost 850. It should go back to its normal idle range of 600 to 700, but it doesnt. Any one know?

 

Make sure the car is warmed up, in neutral, AC off, then remove the TPS harness, start the car and rev to 2-3K for a couple of seconds. Set to 650...double check it by blipping the throttle, then stop the engine and reconnect the TPS harness. The idle will most likely go up, so that's ok. If you have an automatic, reset the DTC per factory manual instructions.

If that doesn't work....check to make sure you don't have a tight throttle cable, and that you haven't mistakenly screwed in the metal TB stop screw to adjust the idle speed.

 

i did it man, exactly as u described, dissconnected tps adjusted to 650, shut engine off connected back tps start the car and again 900rpm.... also can't be tps because i replaced it with TB from different max, also checked resisstance and everything seems fine....
what is DTC can i reset it (btw im auto)
checked cables, both look ok

 

i think he meant reset the onboard computer. just use the flathead screwdriver method works fine. instructions for that are in the how-to's if you aren't sure how.

 

Make sure the throttle cable is adjusted correctly. You should loosen the nut on the accelerator cable and tighten until the throttle cam just starts to move. Then back off 1.5 to 2.0 turns. Also make sure you don't have the TB stop screw screwed in too far. You should be able to adjust the idle to 650 +-50 rpm. If not, you've got the throttle cable too tight or stop screw turned in too far. Another possible cause could be an air leak...that will always raise the idle RPM.

Also....I did mean the DTC computer which is for the auto. It's a fairly long, but easy procedure that's in the factory manual. Takes about a minute or two to run thru it. It clears the codes caused by you disconnecting the TPS. The procedure might be on a sticky or old thread.

BTW...I checked my idle and it runs about 750 to 800 with the climate control on. I think the computer adjusts it for driveability sake...in other words..that's normal.
