The car situation:
This car is 2010 Honda front range 1.5 manual transmission car emissions, has traveled 60,628 km, normal maintenance without incident.
Analysis:
This reflects the recent one week car owners often automatically turn off in the road. The owner said the car always like to step on the clutch when the stall. Through this analysis should be in addition to the issue of this car idling system.
Connect the instrument into the engine system and found no fault codes, by-cylinder injector plug unplug, found no shortage of cylinders phenomenon. Since there is no fault lights no fault code, it is possible to suspect individual plug loose virtual access, so individual plug shaking a bit, and some re-install the plug pulled down. Read the data stream in the absence of fault code situation is the best approach. Connect the instrument to read the data stream again, this time suddenly find fault lights up. This reflects the owner when the car is easy to turn off the road, there may be cold when the car is easy to turn off, the car is not easy to turn off the heat after. After the hot car, the engine idling can idle jitter, speed at 500 rpm or so, test procedure does not turn off. The data show that the new parts is no problem, the problem is still there in the intake system. I think of the air flow meter so dirty to prove the owner was not regular maintenance of vehicles, the throttle opening data properly, and do not represent the intake air throttle normal. Decided to remove the throttle cleaning, after completion of loading and cleaning the throttle to match. The experiment again, this time the car engine back to normal, smooth idling, driving road test, vehicle acceleration and powerful, no flameout phenomenon.
Troubleshooting:
In order to determine whether the air flow meter or damage caused by fouling throttle or two failures exist, re-loading again faulty sensor, intake remains found less, thus proving that this car is a failure for two an air flow meter is damaged throttle fouling.
