Have installed a throttle body spacer for 1995 honda civic from OBX racing sports, almost done but my cable adjustment bracket has to be moved , so there is a bracket that came with the spacer and i dont know where it goes.

There are two coolant lines that connect to this Honda IAC to help quiet the operation of the valve. The part number for a OBDI 1992-1995 Honda Civic Idle Air Controller is 36450-P28-A01. While the OBDII version of this valve is 36450-P2J-J01, and the two units are very similar in design and execution. The EACV or Electronic Air Control Valve is a big part of maintaining your Honda Civic idle. If you've checked your IAC and your Honda still suffers from a surging idle, check your FITV. This Honda Idle Air Controller or IAC is under the throttle body and incorporates into the throttle body passages o locate your Fast Idle Thermo Valve, remove the intake snorkel and locate the FITV beneath your throttle body opening. If your SOHC engine is still having problems, check our guides above on how to check your FITV as well as your IAC. To check this operation, remove your air intake pipe and use your fingers to plug the passages in the lower left hand corner of your throttle body opening. If your idle surge does not go away, unplug your Idle Air Control valve and if that stops your idle surge, your IACV must be replaced. Follow our instructions on how to replace your Honda Civic Idle Air Control Valve. Need to raise your Honda Civic idle or having problems maintaining idle? You can adjust the base idle by unscrewing or screwing in the Idle screw on your throttle body. This screw allows air to bleed into the passages on the backside of your throttle body, as shown above. To learn how to adjust Honda Civic idle speed, you will not need to remove anything. With a standard screwdriver, simply locate your throttle body and Idle screw.

These are fairly easy and straight forward to replace.

• Start by removing the cable from the accelerator pedal. Climb under the dash and locate the cable at the back side of the pedal near the top. The cable is similar to the brake cable on a bike that has a knob at each end of it to retain it on the component. You can remove this by turning the cable so that it can slide out the notch on the side of the bracket and slide the knob out.
• Next remove the cable from the throttle body. This is done very similar to what you just did under the dash. Turn the round bracket attached to the throttle body that the cable is wrapped around until the cable is loose and you can slide it through the notch in the side and slide the knob out.
• Remove the cable from the mounting bracket. There are two 10mm nuts that lock it into place on the bracket.
• Trace the throttle cable back to the firewall and remove it from all of the retaining clips.
• Pull the cable through the firewall. The rubber grommet will come with it.
• Install the new cable in the reverse order.
• When you are re-installing the two 10mm nuts near the throttle body, these nuts are used for the adjustments. When the cable is installed on the throttle body, it doesn't need to be really tight, in fact there should be a slight amount of play in the cable. You can use the two 10mm nuts to adjust this.

Good Luck!

to ajust the detent cable have someone push the accelerater down inside while you ajust the position at the carb. or throttle body

Idle Air Control Valve Pintle may be bad If you disconnect the IAC and the problem ceases it can point to this being the problem.: Removal & Installation 3.5L Engine To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Remove the fuel injector sight shield.
3. Drain the cooling system.
4. Remove or disconnect the following:
   • The air cleaner intake duct. Figure of IAC and TPS electrical connectors disconnected.
     
     
   • The idle air control (IAC) valve and throttle position (TP) sensor electrical connectors. Figure of cruise control and throttle control cables removed from throttle lever.
     
     
   • The cruise control cable and throttle control cable from the throttle body lever.
   • The fuel pressure regulator vacuum hose, positive crankcase ventilation (PCV) hose and the throttle body vacuum port hose.
   • The throttle body coolant hoses.
   • The throttle control cable bracket, leaving the throttle and cruise cables connected.
   • The upper nut holding the throttle body to the intake manifold.
   • The throttle body assembly.
5. Clean the gasket mating surfaces.

To Install:

1. Install a new gasket and new studs if necessary.
2. Install or connect the following:
   • The throttle body assembly.
   • Start the top nut by hand.
   • The throttle body coolant hoses.
   • Position the throttle control cable bracket and hand start the retaining nuts and bolt.
   • Torque the three throttle body retaining nuts to 89 in.lbs. (10 Nm). And the bracket retaining bolt to 115 in.lbs. (13 Nm).
   • The throttle body vacuum port hose, PCV valve hose and the fuel pressure regulator hose.
   • The throttle control and cruise control cables to the throttle body lever.
   • The IAC valve and TP sensor electrical connectors.
   • The air intake duct.
3. Refill the cooling system.
4. Install the fuel injector sight shield.

4.0L Engine To Remove:

Vacuum leak or fast idle sensor inside throttle body. Also check to make sure throttle cable and cruise control cable is not out of place on the cable roller/pulley on top of intake manifold.

look under car where cable from lever attaches to split plate to operate cables for each wheel. there is a spring loaded rod there that can be adjusted with 2 wrenches. one to hold the rod and the other to move adjustment nut assembly. chris

some times when you put performance parts you have to adjust the gas flow to the engine and check you IDLE CONTROL VALVE that would cause reving on your car and your friends car also

find your cable that goes to your throttle body and look for a screw on a fixed plate, the screw should be touching a cam leaver for the throttle butterfly. if the is no screw it may have rattled out and you may have lost it. Or the idle is done by the computer i in the case you may have a fuilty sensor or computer.

here is a link for a performance throttle body they aren't cheap though...........no luck finding a rebuild kit sorry :(
