Pontiac GTO 2004-2006 - help car dying after running p0101 code

I have a 2004 gto, torquer v2 cam full bolt on car. Was tuned back in April. Car had absolutely no issues until recently. When I start the car it runs fine, goes into closed loop no issues. I can drive the car a bit and if I come to a stop light it stumbles, sometimes dies and throws a p0101 code. I have no vacuum leaks and all the sensors are specing out fine. Have tried 3 different MAF sensors and all have the same result. Has anyone had this issue and if so what did you do to resolve the problem as its driving me crazy!!!

I know this is basic and dumb but did you make sure the maf is pointing the right way? Also what throttle body are you running? Does the car idle fine?

Yes the MAF is in there correctly and its a stock ported tb. Car idles fine for little bit and then dies. The MAF starts out at 1.7lb/m then slowly falls to 1.01lb/m and thats when I get my code.

Have you cleaned the maf up? What intake are you running?

something is restricting the air my good man...the maf should read alot more air then that...normally should read any where from 6.5 to 8.5....

Yes, everything is cleaned there is nothing dirty that would be the problem. Its a k/n

Even with the filter off thats what it still reads.... The car runs fine when it is pulling ~1.5 but its when it drops below 1.0 that it starts acting up and it is only when the car has been running for a while and gets hot, as if it is loading up with fuel or the pcm is getting too hot IDK this is pissing me off because I have checked so many things and it still has the problem

coolant temp sensor

Got it fixed. Was the maximum delta in the tune.
