zero degrees top dead center with an idle speed of 5-10 mph
Timing and idle setting maybe computer controlled and not adjustable. If they are adjustable should be 825-850 RPM
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.
The idle speed is set at the factory and is NOT adjustable.
Yes.
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.
try adjusting the ignition timing(or getting a mechanic to do it)
There is a sticker under the hood that tells what to set the timing to and at what idle speed.
The idle is preset and controlled by the Idle Air Control Motor. You may have a dirty throttle plate that could cause a problem.
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
Driver error.
The correct ignition timing for a 1991 Chevrolet Camaro typically ranges from 0 to 12 degrees before top dead center (BTDC) at idle, depending on the engine type and specific configuration. For optimal performance, it’s best to refer to the owner’s manual or a service manual that corresponds to your engine variant. Additionally, ensure that the timing is set with the engine at operating temperature and using the appropriate tools for accuracy. Always verify with the specific engine specifications for your Camaro model.
