I replaced my 1997 J30t engine last week, but now it shifts late-at 3,000-4,000 RPMs. Autozone got a transmission related code.

My 1994 j30 has low engine power. Low acceleration. engine is loud.

I own a 93 Infiniti J30..Ive recently had problems with eratic idling, severe hesitation, and stalling..the stalling would happen in two different way would be right after starting or when pressing the accelorator, the engine would die down and stall..but I would still have electrical/battery power and with flooring the accelerator I could restart the car...but it would also stall in anohter way..while driving, then slowing down ( not sure if it happened when I pressed the breaks or not ) the car would suddenly and completely die.. no engine die down, it would just cut off with absolutely no electrical/battery power and no interior lights or ignition key reaction. After trying different things, I found that there is a red plastic connector attached to the positive battery cable..when I slide it off it's L shape pin, which is connected to the positive battery cable terminal, then reconnect it, the power comes back on in the car and it will start right back up...I dont know if the red connector is supposed to be able to come off its pin or if it is broken, but everytime the car stalls like this..suddenly and with no electrical power..I can disconnect and reconnect this connector and the power will come back on...but when I wiggled and disconnected it with the car running, it did not stall out the car..
So I pulled coeds from the ECU and got a faulty temperature sensor reading... I replaced it, and cleaned the throttle bodies and MAF ( using proper cleaners for both ) and now the idle/hesitaion/die-down stalling problems seems to be fixed..but the car is still cutting off with no electrical power after driving then slowing down..such as to turn a my questions are..what could be causing this, could it have anything to do with pressing the brakes, what is the red connector attached to the positive battery cable terminal and where does it lead?Any help would be greatly appreciated

It was diagnosed with a failed injector on # 1 cylinder

shifter button jams. after many tries it shifts but after many tries, however other times I get in the car and it shifts with no problem.

During the day, my lights are always on, unless the car is completely off, is there a way I can turn them on and off at will?

This past weekend, I lost power to the car. The thermometer reached near the redline, the battery light came on, the brake light came on, and the car eventually lost all power and quit working. I had the car jumped, it started and ran for just over a mile before all these symptoms came up again. I took the battery in, discovering it had very low cold cranking amps. I replaced it, and the car ran fine. This morning, the car lasted for about 10 miles, and all those symptoms appeared again. The battery light is on, the brake liight is on, and the car has a loss in power. Any ideas as to what I may need to do? Also, I have no heat. That stopped working as well.
