Need advice & help. Own a 2000 L.C. w/ 171,000 miles, have changed oil every 3000 miles, is in excellent condition for its age. The only modification I have made under the hood is a Snorkel for the Airflow. I have made many modifications on the exterior of the SUV & Suspension, etc. 1st time I needed to get it smogged for CA registration. It didn't pass, and I am clueless to know why. I didn't have the mechanic do a diagnosis b/c the toyota OEM is reliable and I don't want different parts changed under the hood b/c in my opinion why change toyota reliable parts. Also why would a 2000 LandCruiser that has been taken care of and has had zero problems its entire life, supposedly have a SMOG issue. I think the mechanic was not truthful & that is why I am asking the people I trust here at the IH8MUD Forum. I am lost and do not know what to do except to get it registered in Arizona. Is it possible I will not pass the 2nd SMOG test at a different trusted SMOG check business and why if everything on the SUV has been taken care of and there are no wear issues with the exhaust and catalytic converter, etc. Thank you in advance for anyone's help , experience and advice on this matter.
