i got my TPS set to the correct voltages, but now i'm wondering why i have a high idle (~1500rpm when cold, 1000rpm when warmed up)

in the howto's i found, they said to unscrew the idle air bypass screw on the bottom of the throttle body and i couldn't find it, so i'm guessing thats my problem... can somebody show/tell me where this screw is? i have the throttle stop screw backed all the way out and have the TPS adjusted perfectly for both the narrow and wide range, and i'm guessing the idle is high because of this mystery screw...

The screw is located right under the throttle body. Don't have a picture, but I'll have a shot lol. Locate the fuel cap. Find it and diagnle on the left - 10'oclockish from the fuel cap.

are you talking about the oil fill cap?

rexhvn

Yes the fuel cap lol.. its almost right next to the alternater. Have you got a picture? Even if you pm me the picture.

there are atleast 3 adjustment screws on the UIM that i can think of... one points straight up and is closer to the alternator, one is down by the oil filter pointing straight down, and one is on the top of the UIM pointing towards the drivers side.

rexhvn

My mistake lol... I said fuel cap lol... I ment oil cap... I just released! its the screw closest to the oil cap.

3rd Gen owners are laughing all over the world.....The screw you are looking for is under the throttle body-driver side. Take your hand or an inspection mirror and look directly under the TB where the air inlet elbow bolts on. It is recessed back in a 5/8" diameter home - look for the slot of the screw head.

is it directly on the bottom side of the TB or is it off the back of the TB close to the firewall?

i need a pic of this or something

Here is a picture of where the idle screw is. Its right in the middle of the black circle!

the first pic you posted is where the double throttle plate stop screw is supposed to go. it seems you are missing this.

the second pic you posted is where the main throttle stop screw goes. its an impressed phillips head screw with a lock nut on it. you also seem to be missing this one

also, you can get to that screw with the TB elbow on, right?

S8nana

rexhvn you just made me and other people dumbier by reading your post. Jacob the idle air bleed screw is easy to get to with the elbow on you just need a smaller screwdriver of course...its going to be a flathead(blade) screwdriver. Just feel around and youll feel the hole i guess...Also check for vac leaks you never know. How much was your TPS out of spec. Did the idle change like that after you adjusted it??? I dont see the idle changing that drasctailly if it wasnt even off that much. Also i guess you should also make sure the throttle cable is holding it open etc. good luck on getting your car going...im sure its something simple!

i have the little black catch can for the charcoal canister undernear the TB elbow, so im thinking i cant feel this adjuster screw because its blocking it
