What causes the Changhe Furuida to shake and stall when cold?

[LeRose]

Changhe Furuida shaking and stalling when cold can be caused by a dirty throttle body or severe carbon buildup on the intake valves. Dirty throttle body: When starting a cold engine, insufficient air intake leads to incomplete combustion, but the issue usually resolves itself after a few seconds as the ECU automatically adjusts. Severe carbon buildup on intake valves: Fuel sprayed onto the intake valves during cold starts is mostly absorbed by the carbon deposits, resulting in excessively lean fuel mixture in the cylinders and causing shaking. These two issues are very common. The solution is cleaning. For the first issue, have the throttle body and intake tract cleaned at a 4S shop. For the second issue, use high-quality fuel additives to clean the carbon deposits on the intake valves. These measures should basically solve the problem.

I've been repairing cars for over 20 years, and this kind of cold start stalling issue is quite common. For small cars like the Changhe Furuida, the engine often has problems when starting cold. The main causes could be a clogged fuel system, such as carbon buildup in the fuel injectors or a dirty fuel filter, which blocks the fuel line. When the engine doesn't get enough fuel, it shakes and then stalls. Another issue could be aging spark plugs in the ignition system, causing misfires, especially noticeable in low temperatures. Carbon deposits are also a big problem—when the throttle valve gets too dirty, the air-fuel mixture becomes unbalanced, leading to unstable starts. My advice is not to delay; take it to a professional repair shop for a full inspection. Use cleaning agents to remove carbon deposits or replace the spark plugs. Using high-quality gasoline regularly can prevent such issues. In winter, park away from windy areas and let the engine warm up for 30 seconds before driving—it helps a lot.

I also encountered this issue with my Forland after driving it for a few years. On winter mornings, the car would shake violently like a sieve when starting, then suddenly stall, which gave me quite a scare. Later, it was diagnosed that the air filter was clogged with too much dust, causing insufficient air intake during cold starts and leading to inadequate engine air supply. Loose contacts on the ignition coil also played a role, causing unstable current. For routine maintenance, I change the engine oil and air filter every 5,000 kilometers and clean the fuel injectors, which has made the car much more stable. Don’t forget to check the battery—low voltage can also cause trouble during cold starts. Using genuine spare parts is quite effective and not expensive. Spending a little extra ensures peace of mind on the road and avoids breakdowns midway.

Last month, my car stalled and shook during cold starts, which really freaked me out. I took it to the dealership, and the mechanic said it was an idle speed control valve failure—the thing wouldn't work in low temperatures, causing no ignition. It could also be due to aging sensors giving inaccurate readings, leading to ECU control failure. Replacing the valve fixed the issue, costing just a few hundred bucks. Normally, avoid stomping on the gas pedal to reduce carbon buildup, maintain regular engine servicing, and clean the throttle body occasionally. New drivers should be careful not to force-restart the engine—multiple attempts can damage it.
