Hey guys .. im new here i was doing some research coudn't find something simular so here we go...
I got a 91 crx with a d15 the car drives fine and everything... only problem is that the throttle body gets stuck so the car idles at 2-3k.. and it wont go down unless if i open the hood and move it down ... does anyone have an idea how can i fix this ?
Thanks for looking
Daniel

 

Please someone ?

 

get a new one... Really though it has to be getting stuck for a reason, get in there and see whats getting stuck, maybe you need a new throttle cable.

 

Spring on the TB should pull the cable back.
My guess is that you need to lube your throttle cable.

 

i had the same problem. all i did was spray sum wd40 and tighten my cable back dow when i got the correct idle speed and it was fixed, jus lube it and you should be fine

 

take off the throttle body, and use a die grinder with a disk and sand the center of the 2 screws on the tps so you can put a flat head screw driver in there and twist them out.

take the butterfly out of the center of the port and set it to the side

then undo the screw on the throttle handle, take the throttle, spring and the spacer off

go back to the tps side, take off the shaft with the spring with it.

now go to the butterfly valve and sand the sides and the whole face till you have either a smooth finish or it is shiny

go back to the actual throttle body and clean the ports using a polishing bit on the die grinder and polish it till smooth or shiny

while your at it go ahead and take off the fitv and clean it as well.

respray all your hard parts, except the tps sensor with the wd-40 and possibly some grease with the center spacer between the spring and the housing throttle handle side of the t/b
afer this is done, then re assemble and then put it back on and presto! your done!


note: you have to turn the shaft a little bit foward to make the throttle handle fit back onto the shaft. and you have to turn it a little more foward to put the butterfly valve back into place and make sure TO CENTER IT.


theres a write up on how to clean your fitv valve assembly here some where

 

Thanks for the reply guys .... just got home right now im going to the garage to take a look at my car...
See if i could make something happend..
Thanks once again guys.. i'll let u guys know how it goes !

 

Don't take anything apart...yet.
There are 2 reasond for this to happen to an unmodified TB. One is the throttle cable being old and the steel wire inside needs some lube to slide easily again. Two is oil vapors build up
inside the TB. Both can be fixed with WD-40. Use a rag to clean the inside of the TB and spray WD-40 inside to help remove some of the build up.

 

3. the spring on the throttle body becomes sprung. it doesn't seem to let the cable fully retract.

 

Maxbore, and jhmmond good stuffs...
Yesterday night i tried thighten the wire.. but it didnt work ..
To be exact .. the wire have like just a little play on it ( little lose)...
The arm that moves up and down pulling the wire... doesnt want to go in all the way..
Maybe a 1/2 inch or less could it be the vacum line ? ( if there is one ) lol

 

true but i was just speaking on how to completely clean the t/b plus if you spray wd-40 on certain parts of the t/b some parts will fack up like the tps(it happened to me) and the map as well. i just suggested doing it this way because you dont take the risk of messing up anything...as long as you know what your doing.

 

try revving the car up. when the rpms do get stuck, go to the engine bay, and try to retract the cable by pulling on the cable bracket on the tb. or, remove the throttle body, and clean that thing. or to be better off, send it to maxbore and let him take care of the cleaning, and porting it out.
