What is the ignition jitter of Picasso's cold car?

Regarding your question, first of all, let's talk about the failure of unstable idle speed, which is mainly caused by carbon deposition. We mainly check the carbon deposition of throttle body, air intake and fuel injector. If the vehicle is used in urban areas for a long time, we suggest that you clean the throttle body every 65,438+05,000 kilometers and the air intake and fuel injector every 30,000 kilometers. Spark plugs need to be replaced every 30,000 kilometers. The key point is to check the working condition of spark plug and ignition coil. Generally, the failure of oil burning is due to the damage of the valve oil seal, and the cylinder head needs to be removed before it can be repaired and replaced. I hope my answer is helpful to you.
