SOURCE: idle too high +goes higher when put in gear (manual transmision

IAC valve problem. Nissan has a updated harness (with one way diode inside of the harness) to prevent backfeeding for the IAC valve and a new IAC valve also gets installed. That's where I would look. IAC valve or "idle air control" valve.

SOURCE: 94 nissan quest has started idling at 500 rpm. I

Jeff did you figure this out. I am dealing with the exact same thing currently. Things to look at are Mass Air Flow Sensor (MAF), Throttle position Sensor (TPS), Air Idle control valve. I have played with everything but the Air control valve. I tried three different MAF, including a ghost sensor (circuit to match ressitance). I'm going to investigate the air idle control tommorrow. Let me know if this helps or if you get it figured oot

SOURCE: 2002 altima idling too high check engine light on

The first and easiest thing you should do or have someone do, is check under the hood for a vacuum leak, possibly coming from a cracked or broken hose. Check and inspect all rubber hoses, including the large ribbed hose running to the throttle body (Engine air intake from the air filter box). You can hear a leak if it is loud enough and will sound like a hiss. Your engine is idling high because of a vacuum leak.

Toyota Rav 4 1997 .Check engine comes on .Codes are P0301,302,303,304116 . What to do.


The engine coolant temperature is high. Your other Codes are for missing cylinders on cylinder 1,2,3,and 4. Get the Codes cleared and start over. Changing the plugs and wires,etc could have generated the missing cylinder Codes.

Autozone,Advance, and Oreilys will scan for free.

Check your engine for an IDLE SPEED CONTROL SOLENOID, which may be in the intake. Or a fuel pressure regulator.

A lot of times people work on the spark side and forget the fuel injectors. They can cause a miss.

Its idling rough


Hi.

Check idle air control system (valve, hoses and wires). Check air intake and check the sensors installed in the air intake. Check vacuum for leaks.

Those listed are the most common faults causing fast idle in this type of engine.
