04 chevy colorado running rich
I removed my muffler a month or so back and noticed some possible effect of reduced back pressure. I think my truck is running rich because there is a strong smell of fuel on start up and whenever I go to stop it starts to bog down and almost die. It must be due to the lack of back pressure because it started when I removed the muffler. I was just wondering if there was a way to retune the fuel/air mixture without having to replace the muffler. Thanks!
