engine problems

[riley1234]

I have a 2011 ram 1500 SLT 4.7l v8 flex and I have been having some hesitation issues, like when I accelerate threw first gear it like jumps until I get it up to 200 rpms then it runs normal i have already replaced the pcv valve in it and that didn't solve the problem. Also all 4 of my o2 sensors r giving me a code and I have already changed the 4 of them and the code will not go away after clearing it and driving it for a while some people have told me it can be a electrical problem and others have told me the pcm module could be bad and I have checked the wiring for burned or frayed wires and can not figure it out any help would be appreciated

It is almost never the PCM what are the codes you are getting.

200 RPMs?

When sensors start to fail, and multiple sensors like in your case, and with "all of a sudden" hesitation issues particularly at low engine RPMs, take a look at your battery voltage. The ignition circuit requires several amps of power at the correct voltage. An alternator doesn't provide much amperage until engine RPMs get up to around 1,200 RPMs.

Your issues could be as simple as a battery on the cliff of failure.

I meant 2000 rpms but I have fixed the hesitation issue now I just cant figure out the codes for the o2 sensors?

If you fixed it you should share what was done ,it helps people with the same issue.

we also need to know what the codes are.
