Throwing enginue codes P0101, P0131, & P0151...HELP! Hello -
I've been researching thread after thread after thread....
P0101 - Mass or Volume Airflow Circuit Range/Performance
P0131 - O2 circuit Low Voltage (Bank 1, Sensor 1)
P0151 - O2 circuit Low Voltage (Bank 1, Sensor 1?...or 2?)
Anyways...it's a 2002 Trans Am that I recently purchased. Great shape! Firehawk hood with ram air (K&N air filter), headers to tips upgraded exhaust. Of it's 71,000 miles on it, only 400 were put on it in the last 3 years!
The Engine Light comes on when I WOT it....not all the time, but I can usually get it to trip if I get on it for a bit. I have a Preditor tuner, so I have checked/cleared it twice now.
I did take it to a shop and they said where my MAF attaches to my intake was entraining air....however they didn't fix that (it was at a difficult angle, I guess). So, I managed to adjust and tighten up things.
That being said, any ideas on where I should start?
Should I buy a new MAF sensor? (I see stock is okay)
New O2 sensors?
Clean the MAF sensor? How do I do that effectively?
Any help/suggestions is greatly appreciated.
Thanks!

I have a similar problem P0131 P0151 on my LS6 powered 01 Trans Am WS6 (still has stock LS1 MAF/TB/INTAKE(which is LS6 anyway on 01 and 02)/Injectors(also the same on LS1 and LS6 for those years).
I'd love to hear a fix for this...I've done the same thing and read at least 10 or threads and I did read of 1 guy fixing it with a new MAF but mine seems to be okay.
My predator says the MAF reading around 1 lb/min at idle which seems to be right but with how common those 2 codes seem to be I'd love to hear someone say how they fixed the issue and what lead them there.
