hey whats going on everyone i have a 05 ram 4x4 i have a check engine light that says fuel system lean bank one and bank two i was hoping that someone might be able to help me in what might be wrong i also have a code for evap system that says leak detected fuel cap off or loose and i changed the cap out and the problem still continues i wanted to know that if this might be causing the code i have aftermarket exhaust headers and cats and mufflers also i have a short ram air intake any help is useful thanks.

check for an exhaust leak.. what was the exact code?

one of the codes was 442 small leak detected i'll have to put my code reader on it again and find out what the other codes are someone told me that i might have to put restrictor plate between the collector and the exhaust pipe because im allowing to much air to flow through but that would defeat the purpose of me having my free flow exhaust lol let me know what you think.

so i fixed my evap box that code is gone now i only get the one code on both banks it says fuel trim to lean i think it was because i have a aftermarket air intake
