Darn. That woulda been too easy.

Does it run good when cold, and then once it warms start running like crap? (roughly two to three minutes??) If so, disconnect the front O2 sensor(s), and go for a drive. Does the problem go away??

Not that i can tell, it seems to run better and shift smoother once everything is warmed up to operating temp.

im having trouble understanding what you are asking me. Getting to what point is problematic?
As for a pattern, This is my first time getting the lights to reset after i disconnected the cluster, shortly after the lights did come back tho and it was right back to giving me problems , only change was the “No bus” hasnt shown up,

im sorry if im not being very detailed with my writing or if im not explaining things correctly, as this is my first time ever using a forum to help with my issue

Wonder if I am confusing threads again.

Probably.....

Brake and ABS lights will come on for a variety of reasons. If you are still having issues with the speedo dropping out, that is going to be a primary cause, and what you need to fix first.

Understood, from now i will only be focusing on my speedometer problem, i have already replaced the sensor that sits on top of the rear axle, as well as the transmission output shaft speed sensor.

The only time i could get the speedometer/odometer to start working again is when i unplugged my cluster from the back then reconnected it, it only worked for about 30 minutes until it started to cut out again

Try doing a cluster test. Press and hold the Trip/Reset button, turn the ignition on, the test should start pretty quick, when it does, let go of the button. All gauges should run thru their full sweep, and all lights should come on. Ignore any codes that come up, they are essentially meaningless.

i did the cluster test and the only light that DIDNT illuminate was my 4WD light, the Air Bag light was staying light the whole time it was testing, and all gauges did a full sweep. (Didnt get any codes)

So the cluster seems to be good..... unless its an intermittent problem... those are always fun.

Check the wire harness from the rear speed sensor, as far as you can go forward.... See if anything obvious presents itself.
