what is the code for?

 

code 15

 

hey i have a 90 integra gs and my idle does the same thing, i am going to try to fix it this weekend, i have read some threads on another site that say the fiav which is close to the iacv has a little white screw, that comes loose. open up the faiv and titen this screw and you shuold be alright, but other guys say if you tihgten it all the way the idle is still bad until you unscrew the white screw thing i full turn, once i try to fix my idle i will post again and tell you what worked for me good luck

 

code 15 is ignition output, you sure that's the right code?

 

usaully if its the fitv the idle jumps only when cold , and ive never herd of backing it out a turn any one else ? i fixed my fitv and tightened it all the way and was fine . if its the fitv there are 3 - 10 mm bolts then two for the cover on the back oposite the coolant lines i forget what size they are

 

maybe a size eight, but no i never heard of backing it out a turn

 

im pretty sure it throwin code 15..

hey this is another site not specifically for your car but i think the engine is about the same check this out, this is what i am going to do this weekend(use this guide to fix my car)

 

hey i fixed my idle last night, the problem for me happened to be the iacv screens were clogged and completely filthy, (step 6 of the writeup i gave you), idles smoothly now, just thought i'd tell you my problem

 

hey thanks for all da info.i got it fixed it was da map sensor not hooked up...but i have another question...it seem like when i drive it hard my idle bounces up and down..friend say i might need a fuel pressure regulator ...i have itr manfold with 310 injector and aem fuel rail on a stock fuel pressure regulator. do i need to change it?

 

i dont know the answer to that question, but if you check out that site i sent you a link to earlier, i remember reading some threads about the same problem, i just dont know off the top o my head which ones, or what the fix was sry

 

ya my needle jumps up n down sometimes as well add i got error code 14

error code 14 = IAC Sensor
Back of the intake manifold

check manual for correct readings ( Ohms )

 

i got a code 14 also i cleaned the screans of the iacv/eacv and it works fine now, adn now code 14 anymore, you unscrew to bolts, and spray carb cleanor and presto, your done lol, worked for me
