I have a 1992 toyota corolla. It passed the smog test 2 years ago but not this time. My No ppm were around 1300 for 15mph. I barely passed the 25 mph. Everything else was good. Any ideas? Thanks.

I was wondering if you knew where the location is for the EGR valve in a 1992 toyota corolla. I have read some places that they didn't have one that year but I think that is wrong. If you know where the location is, please let me know. Thanks for all your help.
