Idle after header/icebox install
Has anyone adjusted their idle after header/icebox installation? It seems like it is too low now. The car kinda bogs if it is standing still and I turn the wheel or if I lower a window. Let me know what you guys think.

pg ... I did a huge write-up on this a month or so ago. It happened to my car too -- it's just part of the "perks" of adding the icebox and headers. There will be increased vibration and it'll seem like the car shudders when you put a load on the engine by turning the wheel in a standstill, etc.
nothing you can do about it -- other than put the stock stuff back on.

When I had my Civic back in my ricer days I had the same problem and it was solved by raising the idle RPM. I will try this tomorrow morning when I get off work and let you guys know what happens.

I was thinking about an icebox install on mine, but after hearing about the idiling problems i'm not so sure now. Is this a guaranteed "perk" of having the icebox? And are coilovers better than regular spring upgrades?

According to page 11-170 of the Acura 01-03 3.2CL Service Manual:
"The idle learn procedure must be done so the ECU/PCM can learn the engine idle characteristics. Do the idle learn procedure whenever you do any of these actions."
(Following is a lengthy list which includes resetting the ECU/PCM and disconnecting the battery, among other things).
"1. Make sure all electrical items (A/C, audio, rear window defogger, lights, etc.) are off.
2. Start the engine and hold it at 3,000 RPM with no load (in Park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 degrees F (90 degrees C).
3. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes."

If you are talking about tightening the throttle cable, technically it would work but Jens also said this is NOT a good idea at all. it could put too much stress on the cable under WOT and cause it to break, and will also screw with the ECU because the car will never think its idling, it will always think it has the throttle down.
