i have a b16a1 in a 89 crx hf, went the car is cold and i go to crank it it starts up and then the idle shoots up to 2000 rpm somtimes 2 1/4, and when the thermostat opens it goes to 1500 rpm what could be the problem? help will be appreciated

 

try adjusting your idle.

does your car shake? or idle rough.. maybe it's the pcv valve

 

ok

 

See #14 that is the cold idle control valve. I just fixed mine this weekend.

Take that sucker off(3-10mm bolts) and unbolt the back plate (2-8mm bolts), clean the inside and tighten the white piece all the way down.

The pic above shows that it's on the TB cause it's an OBD1 pic, but on the OBD0 cars it's on the IM.

 

would a pvc fix my idle plm it always stay at 500 to 750 rpm most of the time

it would help a little bit.. try cleaning your tb too.. with some throttle body air cleaner mine idled bad before, but when i replaced the pcv valve the idle went a little smoother than before

 

so where is it located ?

 

i had the same problem with mine , but i believe its called the fitv is #14 in the diagram , just do as they said above tighten the white piece and it should fix it mine idles great now

 

does my 91 si engine have fitv ? and it is right under the throttle body right ?

 

im not sure on that one skipmic2006

anyone??

 

me either man ... i want to get this fixed!@

 

check and make sure all your vaccum hoses are in the right places.
