I have had a high negative long term fuel trim for some time now. Car has a rough idle but still runs fine and has some power from a stop. Drive 60 miles a day, 6 days a week. Pulled a wire off a cylinder and didn’t see a change on my ob2 reader. I then pulled the next three off individually and there was no change noticed. When I pulled the injectors off individually I did notice a huge increase in stft before I reconnected. Changed valve cover gasket very recently. Any ideas of why my car runs fine but I have these issues?
