P0101 code on 05 lq4 Looking for some pointers on how I can get a p0101(maf circuit out of range) code to go away, truck was originally drive by wire, I swapped it to drive by cable with a nnbs intake and a 92mm throttle body, I’ve tried a new maf sensor, new air filter, smoked the intake for vaccum leaks and found it leaking out of the throttle blade shaft(it was an Amazon cheapie throttle body) ordered the fitech throttle body from jegs to try a new throttle body, still has the same code, any help is appreciated. Truck is Fbo cam heads if that makes Any difference, I’m not sure I’d the code has always been on even before the intake and tb swap, engine light on the cluster is burnt out and I just came to realize that

You need to be able to see exactly what the MAF is reading. Do you have a scanner capable of doing so? Either way, if the new sensor didn't fix the issue, you likely have a wiring problem somewhere. Get a DVOM and start testing.
