before we tell you, what reason do you have to adjust it? the idle is
automatically controlled by the car's engine management computer, so if
you have a problem, it's generally /not/ a simple matter of adjusting
the idle screw. describe your symptoms and the car's history.

yup. playing with it is only going to mask the real problem and make it
that much harder to diagnose.

My brother's civic engine service light came on. extraction of the code
revealed that the primary O2 sensor on the catalytic converter was a
problem. we changed it but now the idel is a little rough then before. the
service light no longer comes on.

i check the timing and its okay. the idle seemed on the low side. but we
do not know what it should be. i have a tech. but even if i find its low,
how can i adjust the idle? where is the idle screw?

its been almost 2 years, but when i got the code on my 98 civic, i think
it said primary O2 sensor heater circuit malfunction, or something like
that. the engine was running rough and stalling at stop signs, 2 things
it had NEVER done before.

the helm manual told me the primary was the one in the exhaust manifold,
and gave me the spec for the black heater wires. the ohmmeter read 0,
meaning it was a broken/open circuit.

doublechecked on the secondary/bottom O2 sensor on the catalyst. got a
reading within spec. doublechecked the top one. still nothing.

so i replaced the one screwed into the manifold, and everythings been
great since. dealer price was about $220 for it. kragen and autozone
were both out of stock on aftermarket ones, and i forgot to try NAPA.
didnt want to wait to order one online from majestic, but i DID want OEM.

i sure hope you replaced the right one.

The primary is ALWAYS the one BEFORE the last cat.

The secondary is the one AFTER the last cat.

I say "last cat" because some cars have a pre-cat upstream of the regular
one.

i think were kinda hinting that you MAY have replaced the WRONG O2
sensor. replacing the CORRECT one (primary, in the manifold) would solve
the problem and avoid the "ethnic engineering" youre proposing.

dude, for the last time, idle speed adjuster screw is NOT your
problem!!! fix the cause. buy the helm manual if you don't want to
hear what we have to say.
