Question about 2006 Honda CR-V
Just bought a used 2006 CRV 2WD with 40K mi. When idling in D or P, rpm is 700 and a motor vibration is transmitted into the cabin as a rumble and undesired noise level. Riding the brake and giving it a tiny bit of gas to raise the rpm to around 900-1000, everything is smooth. Is there a way to adjust the idle up to 900 rpm?

SOURCE: rough idle stalls at low rpm's
hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The car computer or ECM (electronic control module) receives information from various sensors and will output signals to adjust the IAC motor in or out to adjust engine idle speed by controlling engine idle air.
An IAC motor is highly susceptible to carbon and coking build up; if an IAC goes too long without cleaning it can cause stalling and poor idle quality. Some cars are designed with a large vacuum transfer hose that connects the intake manifold to the IAC (idle air control) motor. If a broken or dilapidated these vacuum lines can cause the engine to lose vacuum which will allow the engine to run rough and die.
Inspect all engine and accessory vacuum lines to look for missing, torn or dilapidated lines and replace as needed. To check the IAC motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the IAC should move in or out.
If the IAC motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the IAC motor is removed clean (use aerosol carburetor cleaner) the passages the IAC uses to control idle air speed.
Good luck and hope this helps

Possible injector failure. locate by disconnecting injectors one at a time. The one that makes no change is the questionable. Status of spark plugs need chkg also. pull the plugs an the one that looks washed is questionable good luck

This sounds like a classic vacuum leak problem. Check under hood to make sure all the hoses are connected or have someone who knows how do it for you. Locate the air sensor in the fresh air intake stream and make sure there are no leaks between it and the engine.
