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.
