今天看了一辆2000 ACURA INTEGRA 1.8, CHECK ENGINE LIGHT ON, CODE P0172, FUEL TRIM TOO RICH. 本来以为很简单,做起来才知道麻烦。下面的是已经检查过的。
FUEL PRESSURE--OK 35 PSI IDLE, 45 PSI WOT
TIMING -----------OK 16 BTDC WITH CONNECTOR JUMPED
MAP SENSOR------OK
OXYGENG SENSOR-OK FRONT AND BACK ARE WORKING
EVAP SOLENOID----OK NOT LEAKING
EXAUST SYSEM-----OK NO CRACK
最近有一辆车弄得我头脑发昏,特上来看有没有那位大虾能帮帮忙。
这是一辆1987 TOYOTA CELICA 2.0L , ENGINE 3S-GE.
CAR CAME IN NO SPARK, 检查过
DISTRIBUTOR--OK
IGNITION COIL--OK
IGNITOR---OK
ECM( COMPUTER) ---OK
ECM MAIN GROUND & POWER---OK
车子有时候IDLE一两个小时都没问题,但把车TURN OFF, 就有可能打不着了。
据我的观察,IF THE CHECK ENGINE LIGHT ON WHEN THE KEY ON, THEN THE CAR CAN START. IF CHECK ENGINE LIGHT OFF WHEN THE KEY ON, THEN THE CAR CAN ONLY CRANK BUT NO START.
印度一新移民拿了个dell laptop, 不能上网,打开control panel, 上面说:“ connect to unidentify network, but not conneted to internet". 可是我换了个加拿大本地的desktop上去,马上就可以上网了,这是为啥呢?用的是shaw cable high speed internet, 有经过Belkin router, cat 5 接出来的。
