Q: I have a 1992 Honda Accord sedan, because the engine on the highway when the engine lubricating oil blockage, damage to the engine. Replacement of a model for the F20A second-hand engine, there was a stall out of the fault, the repair staff suspected to be automatic transmission failure, so for a second-hand automatic transmission, but the fault remains the same. Until now, the car has been in the repair shop for half a month, repair workers are unable to start. Can you tell me what can cause such a failure?
    A: I do not know how you repair the technical level of vehicle maintenance, how familiar with this model and whether there is a dedicated fault diagnostic apparatus. A good repair shop will not be carefully checked in the case of free replacement parts, but should use the diagnostic equipment to determine the fault location and then change parts. If the repair shop at every turn for the parts for testing, then the replacement parts have not ruled out the case of failure will be able to do nothing
    Because your description of the vehicle malfunction is too simple, you can only briefly talk about the general inspection steps for this failure. This car is in the replacement of the engine after the stall flame failure, and this is a second-hand engine, so you should first determine the performance of this engine is good, and the work of the various conditions are normal. In the gear after the gears need to output a larger power, if the engine idle or output power is insufficient, will inevitably lead to engine stall flameout. From the fault phenomenon you describe, the car's fault should focus on the engine, it is recommended to carefully check the engine and then automatic transmission repair.
    (1) use the fault diagnosis machine to check the body computer fault storage, see if there is a fault code, and observe the data flow in the sensor signal value is normal. Or short fault diagnosis socket, read the instrument on the fault flashing code. If there is a fault code should figure out its meaning and be used as a reference for troubleshooting.
    (2) to run the engine and observe its work, such as whether the idle speed jitter, exhaust emissions are normal, to speed up the phenomenon of tempering or blasting. If the engine is abnormal, it should check its oil, circuit and mechanical parts to find out the cause.
    (3) In ensuring the engine performance is good, should focus on checking the engine and transmission between the wiring harness and transmission torque converter within the lock clutch.
