Why does the Encores idle fluctuate in the morning?

Check if the three-way catalytic converter is clogged and replace it in time. Here is the relevant information: 1. Engine introduction: The Encore uses two engines in total, one is a 1.0-liter turbocharged engine, and the other is a 1.3-liter turbocharged engine. The wheelbase of the Encore is 2570mm, and the length, width, and height are 4295mm, 1798mm, and 1607mm respectively. 2. 1.0-liter turbocharged engine: The Encore's 1.0-liter turbocharged engine has a maximum power of 125 horsepower and a maximum torque of 180 Nm. The maximum power speed of this engine is 5800 rpm, and the maximum torque speed is 1350 to 4500 rpm.
I've had this Enclave for over a year, and every morning when starting it, the idle speed fluctuates up and down, sometimes at 1000 RPM and other times at 1500 RPM, which is quite annoying. Later, I checked it myself and found carbon buildup on the throttle body. The carbon deposits were blocking the throttle body, causing unstable air intake, and the computer couldn't adjust properly. Additionally, the mass air flow sensor might be a bit dirty—summer dust can easily affect its readings. I tried cleaning the throttle body and the sensor, and now it's much better. If this continues for a long time, not only will driving be uncomfortable, but it will also increase fuel consumption, leading to more frequent trips to the gas station. It's best to address it early and not wait until winter when the low temperatures make it worse, to avoid spending a lot on engine repairs or other major fixes.
