Ke Luzi 1.8 automatic refueling machine when suddenly there is the loud sounds like gear slippage. One seconds click on a file. What happened nextI've just finished the engine. When the car is idle and unstable, it's time to put out the fire. Just pull the intake pressure sensor outIn the machine on the gearbox there like a steaming sound, in the left front tire there sounds more.
I'll give you a answer to this question, because I have encountered similar situations many times.After the end of engine overhaul, especially Shanghai GM car, when car idle wear everything is normal, but to open out the test, then pull the trip to tell, a problem, a fierce oil, car gedeng jump, jump again after all normal, traffic lights, and intermittent pumping hair. The idle speed fluctuated, with computer back to re learn the idle or the dead.Then I thought it was carbon deposition, but where did the new engine come of carbon, so my head exploded.Finally, finally, find the problem, the intake pressure sensor, processing method is very simple, with cleaning agent for cleaning up go, don't pull. The reason is that in the engine damage after the intake pressure disturbance, when coupled with your overhaul of the engine, the pressure sensor is placed in the outer space, there will be oil and dust in the above, so that the sensor signal is chaotic, causing the above fault.Of course, do not rule out the sensor itself damage caused by the phenomenon, so I suggest you, if the cleaning is not normal, then change it directly.Other reasons include: 1, the oil quality of gasoline will also affect; in general, I repair the engine, the vehicle's oil circuit is to be cleaned, the oil needs to be replaced.2, the replacement of spark plugs.3, the replacement of the gasoline filter.But after two, you have to get rid of the estimate, you know!

Is there any fault with the computer?
