I have a 1989 firebird and the emissions are sky high. I just recently got the car and just need to get the emissions down to get a sticker. Does and body have any tips on how to lower them. Any feed back would be much appreciated!!

 

Check for vacuum leaks. Check for trouble codes. Replace the O2 sensor.

 

It is leaking from the rear main seal I think.. Not sure though and where is the o2 sensor located and how could i check if it is shot? Check engine light comes on and goes off as it pleases lol.
