Just got the PCM back, and have 2 new codes, P0131 /p0151, it has a little hesitation while driving, Cleaned the MAF.....any Ideas, O2 sensors?

P0131 is your left side oxygen sensor low voltage circuit.
P0151 is your right side oxygen sensor low voltage circuit.

Do you have a regular scanner that can read the O2 voltages? Seems odd they would both be out at the same time. Did you install the headers? If so, ensure the wiring harnesses didn't touch the headers.

i Have not installed the headers yet, I had the tune done done with headers. I will install them this weekend and rescan. I will post some freeze frame data later, thanks. How is Vilseck, have not been up there in a while

It finally warmed up some. But, the training area is still in my backyard which stinks!

So, installed the headers, Tune was done by frost, Switched out MAF sensor with new one, Fuel pump is only 2 yrs old as well as filter..........Any ideas??

Is the hesitation under WOT or just normal driving? You need to take an 02 sensor reading after the engine is warm. A bad O2 sensor will usually read around 100mv or below. Also, did any symptoms start after putting fuel in the car? I pumped a full tank of crappy fuel when I was in Georgia. It caused numerous codes to start and I actually changed the MAF out. It took some time to clear up.

Its fine during WOT, it hesitates under light throttle.....checked for vacuum leak with some carb cleaner no leaks....I am hoping its the 02's i have always had the ses light on for a while, just never had read the codes until recently. If i was to buy o2 sensors what brand do you recommend??

I use NTK oxygen sensors. They seem to hold up to the nitrous. Here is the link from Summit for a 1998 Camaro.
