Its time once again for the dreaded california smog test. Can anyone give me some advice or pointers on making sure I pass smog on my 1995 850t 2.3 engine? I had a bad experience with the last one. I had a bad evap purge solenoid and it cost me around 499.00 for them to test /diagnose/repair and retest and pull the old "we need to smoke the system" rip off on me. What can I do to improve my chances of passing the first time around?
