I have a 98 3.8 L mustang. It idles fine and can floor it with no hesitation. When I put it in drive and go to get on it it bogs down like its suffocating or something. Any suggestions on what might be causing this issue? I replaced the sensor before the throttle body and no change. Please help!!

 

Clogged cats? If it does it worse when it's warmed up that could be it.
