I have a 3.8 V6 wrangler and it has a problem with afr. the exhaust smells very bad and it runs really rich. I am new to tuning world. I need help to get it running. The car starts up stays on for 2-3 secounds and stalls. I have HP tuner and would live to make changed to adjust its afr. where can I make some changes to make my car idle normal?

Before we go too much further, what has been done that's caused the poor running? Do you have a wideband to validate what the actual AFR is?
