Squeal on acceleration

I have the car listed above Police Interceptor. There is a squealing every time to step on the accelerator that just started a couple weeks ago. Took the belt off to see if it was that, still did the same thing, which also checked and ruled out pulleys. It doesn't squeal at idle though or when letting off the accelerator. Seems to have lost a little power as well once this started.

Good morning,

Without the serpentine belt and still squealing, it could be internal in the engine or a transmission issue.

Can you upload a video of the noise so I can hear it?

I was going to replace the intake manifold and EGR value and pipe as one person told me it sounded like an air issue. But I don't know.

Okay, thanks

This sounds like something is hitting the flywheel at the back of the motor. Check the starter and make sure that the plate is not hitting the flywheel.

Either that or the bolts holding the flywheel to the torque converter are loose.
