What RPM is normal for a 305 at idle speed?
Due to the emissions control sensitivity,The idle can vary between 500 and about 2500 RPM. If you are adjusting the idle without a meter,etc. ,you want it running fairly low without stalling when it's hot. You will need to tweek it most likely when the weather changes.
Engines that run generators don't normally idle. As soon as you start one, the engine immediately comes up to operating speed, usually 1800 or 3600 RPM for North America, and 1500 or 3000 RPM for Europe. There is a governor that keeps the engine at this speed. It does have an adjustment, but this is for normal operating speed, not idle. Many models of portable generators have manuals that can be downloaded. Check the manufacturers…
Generally, that is caused by the engine idle RPM going below normal. When stopping, you take your foot off of the accelerator pedal, and the engine returns to idle. The oil pump RPM and output is directly proportional to the engine RPM and if the idle speed is below that required to maintain normal oil pressure then the guage will indicate it. There could be several causes for this: idle speed set too low, worn…
Why does your gmc sierra idle 1500 rpm yet when you shut it off and restart it will go to normal rpm?
Why does your 91 Montero Idle at 2000rpm when first started cold but turning on the AC will bring it down to a normal cold idle speed for 5 to 10 seconds before going back to 2000rpm?
The Montero has an automatic Idle Speed control. The idle is automatically set during operation by the vehicles engine control module. If the vehicle stays at the 2000 RPM idle, check vacuum lines for leaks, replace the fuel and air filter, and check the timing. All of these can cause the ecm to improperly compensate. However, it is normal for the Montero to 'high-idle' often, especially when using the air conditioner.
no engine starts at 3000 rpm, most stardarded idle speed is 750 rpm......<---HES RIGHT ABOUT THE IDLE PART BUT ENGINES START AT AROUND 15-1700 RPM THEN QUICKLY GO DOWN TO 650-900 RPM IDLE SEVERAL THINGS CAN CAUSE THIS "IDLE CONTROL MOTOR" THEY CAN BE REMOVER AND CLEANED IN MOST CASES AND A THROTTLE POSITION SENSOR HAS CAUSED THIS IN THE PAST PDP
