Car repairs for difficult engine shuddering faults

 The car we are looking at today has a very strong engine shudder,

a muffled sound on the accelerator and a lack of power. The owner had the throttle cleaned, the injectors cleaned, the oil circuit cleaned, the spark plugs changed, the ignition coil changed, and the engine foot pads replaced, which was good at the time after the set was finished, but as soon as the car arrived home it started to shake again. In fact, the engine shaking, lack of power, is generally one of the four cylinders is not working well, since the owner of the replacement are replaced, the repair are repaired, now there are two high-voltage wire he has not been replaced, then we start from the high-voltage wire to check, first pull out the high-voltage wire to him, and then use the multimeter to test his resistance, normally his resistance is a few thousand ohms, now his The resistance is more than 5,000 ohms,

and then shake up no poor contact, indicating that this high-voltage wire he does not have a problem, put him back, and then continue to check the other high-voltage wire, also to pull him out, the cause of the problem I found, the ignition coil under all the oil,

if too much oil, it is easy to cause leakage, the cylinder ignition is certainly not good, so the engine will shake. The reason why there is oil here is because the seal inside is not sealed well,

we first go to the auto parts city, buy a set of seals to replace it, a set of four, a total of 20 yuan, the following we change it up, in fact, changing this is particularly simple, the cover of this circle of screws to unscrew it,

the cover can be replaced, see is this 4 bees ring, is this 4 bad, the new is very soft,

the old The old one is already hard as iron, wipe the oil of the seal, and then you can put the cover back on,

because there is oil in it, so we take the spark plug out, wash the oil out of it, wash it with detergent,

wash the oil on the ignition coil head and give it a wash,

and then give it a dry, dry it and give it all back on. The following we start the vehicle to see if the engine is still shaking, a successful start, the power is particularly strong, the engine is particularly stable,

the problem has been completely solved, is it very simple to repair the car, learn a little car repair knowledge every day, you can do it yourself to repair the car!
