Yeah... definitely wait to do that until you resolve the existing engine problem. Not going to solve your problem; was intended as advice for after problem is solved.

Also to add to this the rpm never changes it just acts like fuel starvation

Well, there is a difference between fuel pressure and fuel volume.... Maybe look at volume... a hose can almost be blocked and pressure is the same...

First, I agree with Dave...Resolve the low voltage first -- Forget the dash gauge and use a meter!
Since you now have the lambda working (20 & pulsing), I'd suggest investigating the popping and Control pressure next.
You can verify the fire and order by pulling one plug at a time. You can see/hear RPM drop. If all hit and the RPM drop is fairly even, I'd check the control pressure next. Otherwise, I'd pull the plugs to check their condition and compare them with each other, and, do a compression check.

Just an update: solved mostly
I installed a new idle speed switch, didn’t hook the wires up to the correct terminals
Car drives like a stage 2 now in closed loop mode, idle is perfect and that volt meter won’t budge from 13 no matter how many accessories are on. A slight sputter, going to write that off as fouled plugs/o2 sensor from all the hacking with the mixture.
Will get it with the dwell meter in the coming days along with the new plugs and o2 sensor. Can’t keep the neighbors up with the loudness. Amazing how a simple switch of wires could create such an issue.
Drives like a dream now. Took it down some farm roads that are nice and new and curvy with hills.
