Chrysler Repair: 97 Chrysler Lhs, chrysler lhs, voltage change

Question
Hi Kevin, I am getting codes of 171,172,174 and I'm not sure where to start looking, Is the best place to start with fuel and maybe MAP sensor? I could not hardly get car to even idle for last 3 days and finally got it home last night. I've been looking around the vac lines and checking wires for cracks but didn't see anything really visible. I started car again and was running ok, I don't get it, but also dont trust it to be ok. Any suggestions would be appreciated.
Thanks
Ron
