High NOX solved.... 200

posted by  someone claiming to be Swedish Babe on  Tue Oct 12 03:22 CST 2004 [RELATED]

Hello, My car finally passed the smog test here in CA.after failing for high NOX. The symptoms was pinging and power loss on acceleration and going uphill.I have replaced the cat/in tank fuel pump/ main fuel pump/spark plug/rotor/distributor cap. However, the problem persisted. Finally gave up and took it to a mechanic blocks from my house. He replaced the 02s (it was orig. w/ 180000 miles on it!) and set the timing. Now the car has full power going uphill/acceleration and NOX dropped from 1470 to 680! Hope this helps bricksters who fail smog check for high NOX. By the way, the mechanic charge me $430 for diagnosis and the 02s...... OUCH!
