Idle Adjustment Screw Location on 96 Civic

I have a 1996 Civic LX. I just replaced a bad distributor and I need to adjust the idle speed. However, my repair manual has a picture and description that doesn't match my car. I can't find a screw to adjust the idle and I've read that I shouldn't adjust the throttle assembly. Can someone tell me where to find the adjustment on this engine? Do I need to take off the air cleaner to see it?

Your idle can not be manually adjusted. it is controled by the ecm via the throttle position sensor on the throttle body(tps). you have to have a diagnostic scanner to interface with the ecm to adjust the idle. most service shops have this equipment

You can not adjust the Idle speed unless you reprogram the ecu. If idle is too low since the new distributor, then the distributor's the problem - it's /not/ the idle adjustment! You know you have to use a jumper to set the ignition timing don't you? Otherwise your base timing will be too retarded and idle potentially too low.
The normal low idle speed should be about 750-800rpm.
When setting the timing, make sure the car is properly
warmed up, too. Follow the directions at the on line manual for your 96 Civic at .

On the civic, there's a lead with a yellow cap in the passenger well that needs to be shorted out. A old paper clip stuck into the sockets works fine, It disables the ECU's electronic advance mechanism so the base timing can be set.

Just for note: The OEM rotor is made of a dark gray plastic with a textured surface, instead of the shiny black stuff. The OEM is also one piece, rather than plastic over a metal sleeve. That interface is the one that failes; the sleeve stayed on the shaft and the plastic goes its own way. I don't know what those plastics are, but I bet the Honda part isn't as brittle as the NAPA part. I was a little taken aback by the price of the OEM rotor ($23 US) but it sure beats a towing bill on top of all the hassle. That was why I also bought the OEM cap ($25 US)... now I have a spare cap to ward off evil spirits, too.
Good luck and hope this helps

My distributor is out 96 Honda Civic LX. How hard

Why do you think the Distributor is out? It's not hard to replace if you have the Haynes repair manual for your vehicle and understand how to get to TDC and line up everything. But it is very rare that a Distributor goes out. If it is not turning it is more likely that your timing Belt has broken than the distributor going bad.

Is it an OBD2-generation b16 engine (96 or newer)? If so, are you using the ECU from the car the engine came out of? You'll need to if you aren't, and you'll need the engine bay harness from it as well for things to work perfectly. Have you tried looking for an idle speed adjustment screw? My 300ZX has one on the idle air control valve, and it allows the idle to be adjusted manually. On my 99 Audi A4, I have to use the VagCom computer diagnostic system to adjust idle. I'd imagine on the Civic you can do it with an adjuster screw. Unfortunately I'm not sure where that is - check out and I bet you'll find it there though - that site has a wealth of knowledge and more than a few guys running motor swaps.

Nissan ga15 engine idle adjustment locations

The idle speed is computer controled, it is not adjustable, you most likely have sludge in the throttle valve and the idle speed control air bypass valve, clean them with carb spray with the engine running.
