Multiple Engine Codes being thrown

[dmharwood37]

Hello. I just recently bought a 2007 RAM 1500 5.7 with about 250,000 and it ran fine for a few days and now it is throwing a ton of code. They are P1129, P0300, P0175, and P0174. It is having a really rough idle and is skipping at idle. Im pretty sure the P1129 is the upstream bank 1 O2 sensor, but could that cause bank 2 codes to be thrown as well? Thank you so much

Just a thought: On MY 19, which is 5th Gen, one of my O2 sensors went out. Dealership replaced. I drove 1/4 mile to BK to get a burger and it threw another code. Got my burger, did a 180 and right back to dealer, my SA was not happy, but he good guy and the Dealership then replaced all 4 O2 sensors, up and down, now all good. Just my experience on sensors. But if U replace, USE OEM, not aftermarket, RAM's picky.

ADDED: Lots of codes could be symptom that yer battery is weak also.

Alright thank you. My plan right now is to change that O2 sensor and see what happens. The battery is only a year old, but I'll run a voltage test on it to be sure
