transmission issues and LED lights?

Okay. I've have about reached my limit on this. So I need some help.

Up until 2 days ago, ran and drove perfect. Now I have a shutter while accelerating. I thought it was a misfire, but rpms don't change at all. It feels kind of like Trans issue.
Recently replaced headlights with HID projector lights. All other lights up front stock.

Taillights replaced with LED with resistors wired in from factory. 3rd brake light is LED as well.

Reverse lights have been changed to LED.

I changed the 3rd brake light back to regular bulb, after having to splice connectors because the 3rd brake light wire harness center light was burnt and not working. No apparent change in shuttering.

I pulled codes with both with engine off and on. Only code the reader gave was 172 (O2 sensor)

Thoughts?

95 bronco with 5.0 and e4od.

I believe its any LED in the taillight assemblies or CHMTBL (3rd brake light) that will make an E4OD do funny things. I think ot has to do with the reverse switch running through the lamp circuit. But thats just from reading on here.
