As you face the opening to the throttle body air intake, look to the left and you'll see a slotted brass adjustment screw (may be covered up by sealant). Turn clockwise to decrease idle speed. -- Ian
A 1998 Chevy Prism's idle speed is computer controlled. You will have to take it to a garage to get it set. However, the idle speed could be altered if, say, your spark plugs are seriously worn. Changing them may restore the original idle speed.
The proper idle speed for a 2000 Nissan Frontier V6 is between 700 rpmÊand 800 rpmÊin park or neutral. In gear, the idle speed should be between 650 rpm and 700 rpm.
There isn't one...the idle speed is controlled by the engine management computer and is not adjustable. Idle speed problems are typically caused by a malfunctioning IAC (Idle Air Control valve), dirty throttle plates, or vacuum leaks.
The idle speed is factory pre-set, and no adjustment is available. If the idle is too high, or too low, you will be having other problems that will affect the idle. In cooler temperatures, it will take the engine longer to come out of fast idle, as the engine warms up to operating temp. If the idle is too high/stays at a higher than normal idle, then take the thing to get it repaired. Running a car in gear(automatic transmission) with a higher than normal idle, can damage the transmission.
The idle air control valve will be located by the throttle body.
could it be the thermostat or the fan itself?
The 1991 Acura Integra idle air control valve can be found on the firewall. The valve will be on the drivers side of the firewall.
To fix this: 1. Loosen the distributor and adv timing by turning it counter-clockwise. and/or 2. Locate idle screw (brass, slotted) next to air intake throttle body and back it out till idle speed increases.
Check idle adjustment (rpm) then check timing, then check for misfire-start there.
On a 1992 Acura Vigor idle is adjusted through a idle control valve. Tightening the valve well raise the lower the idle and loosening it will raise it.
replace the Air Idle Control Valve for starters
Idle speed is computer controlled and is not adjustable. If the speed is incorrect check for a stuck idle speed air motor, on the throttle body, and for air flow problems.
You need to replace your IAC Valve (Idle Air Control Valve) It's located in the back of Your Intake Manifold.
The idle on all fuel injected engines is controlled by the engine control module. There are no adjustments to be made. If your idle is high it could be caused by a vacuum leak or a sticking or bad idle air control motor. If you have a check engine light on then you will need to have it scanned for codes.
the cold idle is controlled by the PCM ( power train control module) the computer of the car and idle is not adjustable.
Will vary between 700 and 1000 rpm.
First you must check the ISC motor ( idle speed control) operation. Its located by the throttle body. It controls idle and high idle speeds. Good luck
