UPDATE: FINALLY PASSED SMOG!!- 5MONTHS LATER-6 SMOG TESTS FAILURES!!
ok so in my post i put down everything i did to help my NOX lower for smog test.. did alot of repairs and even though they didnt contribute to much to lower NOX i know i wont have to replace those parts for a while!! in the end, it ended up being my INJECTORS.. they were really dirty. i guess a bit clogged or carbon build up the mechanic said. after he cleaned my injectors my NOX went from 1100ppm to 102ppm passing!
