Hello, I am new to this community and hoping I can find help for my 1999 Infiniti G20. I recently drove it back from south Texas to Missouri. In the cold(er) starts in Missouri, it has no issues. However, in the Texas heat, it takes several turns to start. When I read the OBD II, it comes up as a ”catalyst monitoring” and “EGR system monitoring.” If you have any suggestions, I would greatly appreciate it. It only has 44,000 miles on it, so I am hoping she still has a good amount of life left on her. Thanks in advance!
