spitting and popping while revving

[BLOCK8732]

Whats good TGC its been awhile since i been on. My 8g cut off one day and wouldnt start for nothing. I replaced cam and crank sensor but nothing. After sitting for 5 months i tracked the problem to a blown fuse. I replaced the fuse and the car cranked and ran at idle. After running at idle i decided to rev up the engine and when i did it started to spit and pop. It was popping and sounded like it was coming back through the intake and MAF. So i thought maybe it was out of time so i went back and double checked my timing and it was in time. Car idles fine but when you give it gas it pops and spits. I was thinking it was old gas but i thought i would ask for help first. I did put some gas treatment in but havent started it since. What do you guys think. Thanks in advance

Could be the MAF sensor. Bad TPS too.

Still no luck. Car still doing the same. Wonder if valves are messed up
