adjusting idle on '94 Accord
I've noticed that my idle has gotten pretty low while the car is in drive latey, especially when I have the A/C on. It's been sitting at around 400 rpm or so and the car vibrates as a result. What do I need to do to adjust the idle to about 800 rpm or so?

There is a screw next to the throttle body facing the passenger side. Its hard to get to. A thin slotted long driver is required. Honda says to unplug the IAC and set to 500 rpm with a fully warm engine. This should be 700 roughly with the IAC plugged in. I personally just set to 700 without doing any of that. But don't quote me.

If you leave the IACV plugged in, it will be trying to compensate while you're adjusting.
After adjusting it, plug the IACV back in & let it all cool down. Reset your ECU.
Then start it & let it warm up, all without touching the gas pedal AT ALL. This lets the ECU re-learn the behavior of the idle system.

ok, thanks for the info. I'll try to take care of this this weekend. where is the IACV? I know on my integra it was at the back of the engine bay, on the intake manifold.
