Ako naman ay may i-share sa inyo. A month ago, biglang naging palyado ang '94 GLXi ko. Palyado as 1 spark plug is not working. On and off po iyun. Hindi ko lang pinansin kasi minsanan lang anf nawawala din later on. Nang biglang naging permanente! Pinakita ko sa kaibigan ko'ng mekaniko, spark plug #3 ang suspetsa. Wala po error code!, then biglang nag stop ang engine and cannot be started anymore. May cranking pero walang kuryente. Wow, ignition coil! Appear agad sa reader (...forgot the code). Luckily, may spare sya so we changed. It lasted for a week, then the same palyado effect ay biglang bumalik and permanent na naman. I changed all plugs (all 4 of them), pero same pa rin... #3 is not firing. May kuryente naman. Immediate ako dumaan sa reputable car repair shop. Wala po error code!! Compression test nila pero maganda pa compression ng ITLOG ko. Bakit sila mag-compression test, e, maganda naman idle, walang blow-by. Then I went back to my mechanic friend to diagnose the problem. What we found out is that chamber #3 has no combustion kasi... walang gas na lumalabas sa injector! Amputsa... buti na lang din at may spare sya and we changed the injector. We changed it because when the engine gets hot, RESISTANCE is infinite--meaning open circuit. Faulty na 'yung injector na iyun. Clean po lahat injectors ko. Iyun din ang culprit kung bakit nasira ang ignition coil. 3 plugs are working instead of 4 which made my ECU command the igniter to generate more voltage. Now, it's working fine and with a bit more torque than before. We were also wondering why injector #3 failed, in fact, bihira po nasisira ang mga injectors. Usually clogged lang sila.

So, if ever palyado ang mga ITLOG nyo, ipa-check nyo agad. May kamahalan na po kasi ignition coil at injectors ng mga ITLOG natin,e. Magandang araw po sa inyo....
