Help I Need To Pass Smog!!!
 

Hi I'm new here and I own a 84 GS with 76K miles on it and did not pass smog. I need alot of help with my RX-7 because I am very confused with the emission stuff on it. Well here are the test results. As an atachment.

I dont know if this helps or not but my car makes backfires as i slow the car down from the tailpipe.

Begin by reading this thread on the same page here.

the tech who tested my car said he dosen't know much about about rx-7 but him looking at the numbers he said my cat still is working and most likely it is the carb needing adjustment. what do you guys think. plus i dont have a job so i cant spend too much to geting it to pass, what i dont understand is that it pass smog a year ago. nothing has changed on the car.:wallbash:
