ok so my car just had a leaking fuel injector so i replaced all 8 injectors and pressure tested the 9th injector so all the injectors are good. now after i put the car together there is no long crank it starts right up but it almost wants to stall as if it had a big cam in it. once the car warms up for about 3-5 min it runs fine but if i try to drive it on a cold startup it sputters and when i give it gas its almost like im fluding the motor.

im also throwing a code for a MAF sensor only sometimes.
the car could also use some new wires, previous owner just replaced all the plugs ~3k miles on them

any ideas?
