can some point me to the right direction.... I need to adjust idle for my car. when it's turned on, the odle is very rough.
I changed the plugs and wire.

 

What RPM does it idle at? Did you check your air filter as well? Did it just start happening? Does it when it's cold? warm? both?

 

mines the same deal and i have a 97 2.2 no vtec. idles at about 450-500rpm...normal? new air filter as well.

 

You should not adjust the idle, the computer controls the idle. If your car is idling rough that means something is wrong. You could start by checking IAC, fuel filter, air filter, spark plugs. If no luck keep looking.

 

I changed the air filter, plug and wire. It idles at around 500.

 

With your Idle being too low you need to Check it by disconnecting the electrical connecter from the Idle Air Control (IAC) valve.You'll have to pry out the consealment plug from the TOP of
the throttle.
Turn the screw to obtain the specified idle speed , then turn the engine off. Plug the connecter back in the IAC valve and remove the 7.5 amp BACK UP fuse from the fuse box for ten seconds

This will clear any trouble codes from the ECM's memory.
Then turn on your cars engine and let it Idle for one minute then ReCheck your Idle Speed.Put every thing back like it was connected before you started your project..

Hope this helps your Idle problem...

hey wheel broker bud will this formula work on my 1991 2.2 accord idle is quite low my car when warm idles at 200-400 and idle fluctuate some times jumps between 0-600

 

yep theres a flat head screw on top of your throttle body. turn it to the left to increase the idle. i like it when the iac just starts to hiss.....then its perfect

 

Thanks Lightshow, you took the words right out of my mouth
