Timing and idle setting maybe computer controlled and not adjustable. If they are adjustable should be 825-850 RPM
The idle speed is set at the factory and is NOT adjustable.
The idle speed for a 1991 Toyota Land Cruiser with the 4.0 3FE engine should be set at 650+- 50 RPMs. This is adjusted by the screw just above the throttle position sensor on the middle of the intake plenum. I have a 1991 LC and this is where I adjust after the timing is set.
There is a idle screw on the throttle linkage on the carb that you can turn to increase the idle speed and then hook up your timing light to check the timing.
Idle speed is normal.
There is a sticker under the hood that tells what to set the timing to and at what idle speed.
try adjusting the ignition timing(or getting a mechanic to do it)
under the hood there should be a white sticker with idle speed and timing on it you cannot set timing and idle on a 2.3. all that is controlled by the pcm
The idle is preset and controlled by the Idle Air Control Motor. You may have a dirty throttle plate that could cause a problem.
1982-1985 ..ht4100 (4.1L) timing 10 degrees BTDC in park idle speed is non-adjustable 1982-1985 .. 307 (5.0L) timing is 20 degrees BTDC@ 1100rpm idle speed is non-adustable
This vehicle is probably fuel injected, and there are no provisions for idle adjustment.
The idle speed is computer controlled on a LT1 engine. If it is a little high, try checking for vacuum leaks.
replace the ecm
Most late model engines have fixed (non adustable) timing and idle speed adjustments. If there is a problem with either, it's probably related to an input signal to your car's on board engine management computer.
You shouldn't. The idle speed is set at the fatory. Instead look into testing your TPS and VAM. Check timing and and test O2 sensor.
A general number for timing is around 10 but that can change based on the engine setup. The idle speed also depends on the set up but its about 900-1000 and 700-800 in gear with a stock engine.
Ignition Timing degree B.T.D.C at idle speed 20 degree plus or minus 2 degree
I know the timing is 6 degrees Before TDC but I don't know what the idle RPM is.. I'm trying to find that myself right now...
Computer needs to re-learn the idle. Spark plugs are bad. Valves are not properly gapped. Adjust Idle Speed on Throttle body.
You will want an idle speed between 750 and 900 rpm with the ac on and in gear (if auto).You will want an idle speed between 750 and 900 rpm with the ac on and in gear (if auto).
There is no idle adjustment screw as the idle speed is controlled by the computer. Excessivly high idle is most likely caused by and intake manifold leak, or a bad idle air control valve.
