IT MAKES A POPPING NOISE AND HAS POWER LOSS

1990 Ford Mustang • 171,892 miles

I didn't have this problem til I took the motor out to do I oil pan gasket and did a few perfomance upgrades. I replaced both upper and lower intake, put 26lbs fuel injectors(was 19lbs), 65mm throttle body, 70mm spacer, 75mm mass air flow sensor.

Does it 'pop' from intake or exhaust? Have you perused mustang forums on internet for answers/tips?
