so my 5.7 hemi aev kit has the following symptoms.

runs really bad when its cold out and when you first start it up in the morning. also been getting terrible mileage recently. sometimes feels like its in limp mode and wont go above 3000 rpms when I stomp on it.

has following codes po172 fuel system lean/rich, po131 02 sensor low voltage bank 1 sensor 1, p0151 02 sensor bank 2 sensor 1


by researching the codes they all have similar things in common and say could be faulty 02 sensors, faulty fuel injectors, incorrect fuel pressure, misfiring. etc

so wondering if you guys with hemis have had anything similar happen. was thinking my first step would be 2 new front 02 sensors and maybe a intake air temp sensor.

thanks

 

You probably know this, but you can take it to any dodge dealer for service or any shop experienced with that engine. Another option would be to call AEV. I'm certain they'd help with a diagnosis.
