i can send back your old china maf, no problem. (i think if fixed it...)
a dead maf (or way off, ) is very hard to troubleshoot.
just keep in mind, 300s means all 4 cylinders, the piston slowed down. randomly.
1: lost spark. at all 4 spark plugs.
2: all injectors weak at ll 4 ports or too rich. ( or maf) keep in mind you can unplug the maf, & use limphome to see if it recovers some power.
3: compression weak on all 4 , no.
4: cam to crank bounce, loose timing belt. nah.
