On my older 5.9 Cummins temps would drop way below 190 idling in subzero weather. 140-160 if I remember right. This is with -15 to -40 F temps. 14 2500 CCSB Laramie G56. SOLD: 11 F150 Ecoboost, 03 2500 HO 48RE w/Smarty + Goerend, 01 2500 HO NV5600 w/OFE, Juice + Mach 1.6s. Air filter/PCV valve. Always check the air filter and PCV valve first. A clogged air filter starves an engine of much-needed air, skewing the air/fuel mixture. On the other hand, a stuck or dirty PCV valve allows too much air into the engine. Both will cause your engine to idle roughly or stall when idling. This leads to the 10-second rule mentioned above: If it looks like you will be idling for longer than 10 seconds, turn off the engine and restart when you are ready to drive. It's estimated the Idling versus restarting Idling versus restarting your engine — it’s wasteful and costs you more. This question has been around for a long time and there are lots of myths and just plain bad advice about which uses more fuel; idling or restarting your engine. So let’s get to the facts. Starting a cold engine uses a lot of fuel The most common reason your car is shaking when stopped or at idle is due to worn spark plugs or vacuum leaks. It can also be caused by loose or damaged engine mounts, a worn serpentine belt, a bad fuel pump, or any other fuel-related issues. The first thing you need to do when your car vibrates or shakes at idle is to check the trouble codes Cutting costs and emissions. Switching off your engine can lower your fuel costs. The amount of fuel a vehicle uses while idling ranges from between 0.75L/hour to 1.9L/hour for passenger vehicles 1. At a petrol cost of $3/L for Unleaded 91, that works out to be between $2.25 and $5.70. To give context at a wider scale, the Argonne National idling actually lowers the coolant tem-perature faster than shutting off the engine. In other words, switching off the engine keeps the engine warm longer. Myth 2: Idling is good for your engine. Excessive idling can actually dam-age your engine components, in-cluding cylinders, spark plugs, and exhaust systems. An idling engine is not operating at If I lower the idle timing too much the map will stay in the upper 50kPa range and additional idle timing gets pulled. If I set the idle to 16 degrees that creates too much map. If I set it to 18 degrees the map will settle when the car is at a stop. I don't want to set the idle timing too high to avoid this. K ey Takeaways. Idle time is defined as the time spent waiting during which a machine is either not scheduled to run or waiting to run. The difference to downtime is that, during idle time, the machine is available and functional, whereas, during downtime, it is either unavailable or not functioning.
