get some of that "guaranteed to pass" run it through a tank of gas and have it smogged....it should pass , if u have no cel's....this stuff works, its called
guaranteed to pass
one thing id like to mention is, if u have a vacuum leak or bad 02's or something like that, obviously it wont help

car has 156k. only time it smokes a little is on those cold winter mornings. its just hard to figure why it passed 15mph test and not the 25 mph. i'm thinking intake passages are still clogged up. trying not to spend 400 on a new egr, probably try changing coolant temp sensor and maybe o2's

another year and i fail this stupid test again. all maintenance is up to date. failed twice and then changed out to a used egr valve because nox numbers were in the 1400's for both tests. it then passed the 15 test like it did last year. i seafoamed it bout 3 times and finally passed last year. it actaully had a reading of 0 on the 25 test. might have to break the bank for a new egr since numbers are so erratic??
