Throttle half-slope start jitter

Santana 2000 is shaking at idle speed in the car. When starting halfway up the slope, 1 gear has no power to start, and sometimes the accelerator doesn't come up, so you need to change the neutral position and step on a few feet of oil.

There are several situations of engine jitter, such as gear start jitter, cold start and insufficient three-way catalytic temperature. The most common reason for engine jitter is that the throttle valve is too dirty or the fuel nozzle has too much carbon deposit, because the gasoline adsorbed on the carbon deposit after landing is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is sometimes rare and thick, which leads to idling jitter after cold start. Solution: The company cleans the oil circuit, and checks whether the idle motor has carbon deposit, so it should be cleaned.
