hi there guys i was wondering if u can help me i did somthing so stupid lol i had an idea on cleaning my si throttle body totaly and fuged up somthing well more like for got how to set the screw back well here is a pic of what screw im talking about u see the bit flat head screw near the return line at the top of the throttle body it should be on the left side of the hose hook up well eney one know how to ajust that to stock lmao can some one please help me out thanks

 

oya ps thats not my throttle body thats a buddys lol but same location tho

 

yeah turn your car on and when it is ideling tune the crew right to lower the thrattel and tune it to the left to raise the idel. your idel shoud be around 700 to 800 rpm (ideling) (720 rpm)

that is how you adjusted it.

if you want to be perfect you have to unplug a sensor and do other stuff with it.

 

Correct. Jumper your timing connector. (That takes the computer adjustments out of the mix) Then set it to the correct RPM. Pull the jumper and your done.

 

its a d16a6 throttle body not the one in the pic so is it the same thing for that one ?????

 

Yes, its the same. Make sure you jump the timing connector(I think its on the driver's side harness near alt.).

 

CHILTON says:
1. Start the engine and warm it up to normal operating temperature. (Allow cooling fan to come on at least once)
2. Connect Tachometer
3. Disconnect the 2P connector from the Electronic Air Control Valve (EACV)
4. Set the front wheels in the straight ahead position and check the idle speed with the headlights, cooling fan, rear defroster, blower fan, and air conditioning not operating.
5. Idle Speed should be as follows:
-All Civics and CRX with 1.5L engine 575-675 RPM
-CRX HF 450-550 RPM
-Civic/CRX Si, and 4WD Wagon 500-600RPM

 

what jumper u talking about i have no clue where it is tho i looked and cant find enethying its a 91 civic dx with a mpfi swap

 

Dude, those RPM numbers are off. No I am not blaming you.

As for the connector... Look by the hood prop's hook when in the down position. Should be right by the window washers water lines. It might have a yellow cap on it. It is a two wire connector.

I have also seen them on the otherside of the strut mount by the injector resistor mounted on a piece of metal with a tab.

Check those two spots out and get back.

 

They seemed low to me too, but thats what it said.. sorry for the incorrect info..

 

wow either my tach is off of somthings messed at start it idels at 2000 then drops to 1500 then 1000 after a few min that normal ?????
