What should I do if Zotye T300 cold car starts abnormally?

It may be caused by air leakage in the engine intake pipe, lax sealing of the idle valve, mechanical failure of the engine, excessive carbon deposition or throttle failure. It is recommended to contact the local 4S shop for inspection and maintenance.

Cause of "click" sound in cold start: 1. Hydraulic tappet: Due to the low oil pressure or the wear of the hydraulic tappet itself, air enters the hydraulic tappet, resulting in a "click" sound. 2. Valve clearance: The valve rocker arm is worn, resulting in excessive valve clearance. 3. Dirty throttle: Dirty throttle is caused by the continuous accumulation of sludge and carbon deposits. 4. Working sound of carbon canister solenoid valve: This is a normal sound and can be used continuously. If the noise is too loud, it is recommended to go to the 4S shop for inspection.

Cause of "click" sound in cold start: 1. Three-way catalytic converter: there is a "click" sound within half a minute after cold start, and then there is no click, which is usually the sound generated by the thermal expansion of three-way catalytic converter. 2. Timing part: There is a loud "click" sound during cold start, which is generally caused by wear, elongation and looseness of timing belt or chain. In addition, this sound is caused by the chain tensioner losing its tensioning function. 3. Naughty rubbing sound: If the prompt sound is turned on, the sound may be caused by air conditioning rubbing.

Cause of "Knock-Knock" sound in cold start: 1. The exhaust valve of the fuel tank is not working properly. 2. The fluid in the reflux pump is impacted. 3. The fuel filter is partially blocked.
