Technical experts to resolve cold failure

The diagnostic procedure is:
① check the appearance of the engine, such as vacuum tubes, wiring harness plug off, leak, leakage, oil leakage, water leakage; ② use computer diagnostic equipment to check the fault code and read the data block; ③ with multimeters, oscilloscopes and other instruments instruments to measure; ④ According to the above checks to determine the cause of the malfunction and components, repair or replacement parts; ⑤ The troubleshooting again after the above instrument detection; ⑥ reproduce the failure conditions of the test or road test.
Three failures such as occurred in the new car, such as driving less than 60,000 km, failure largely due to the intake valve, inlet excessive carbon deposition, the nozzle impurities caused by excessive, it is recommended the vehicle driving 20000-30000 km when the engine demolition cleaning, ie, dialysis and intravenous fluids will achieve good results, if only one treatment can not completely rule out the possibility of failure.
