ok first of all its a 90 sport 2 door runs fine well when it wants to that is first major problem i have is the brakes i get in press the brakes to the floor ive completely replaced the front and fixed a leak in the back replaced the booster the master cylinder even adjusted the rear brakes and i still only have front front brakes im lost on it. secont problem something in the front end feels loose when i go offroading and if and when my tires do spin the front wheels seem to move side to side a bit i dont know what it is and how to fix it im afraid if i take it to a specialist they will take me to the creaners. third problem is when i put it in gear forward or reverse it jerks pretty hard i heard they had tranny mount problems but i think it may be more than that like maybe a rear driveshaft or somethign along the lines of that. and my speedo dont work how hard is to change?

ohand also when i take off from a stop light it seems kinda sluggish i kinda can feel it through the gas pedal like a small vibration is that a harmonic balancer or something more severe?

First of all, sounds like you have a lot off issues, I'll try to cover them all and let me know if I miss them. Some more info that we'll need:

Automatic or manual? How many miles?

Brakes: have you bled the system since you did all the work?

Side to side movement: is it your steering wheel moving side to side? If so, it could be your steering stabilizer. But does it wander on the highway?

Putting in gear: sounds like it's an automatic. How many miles since you've replaced the transmission fluid? These trannies like fresh fluid and shifting quality suffers when it is dirty.

Speedo: not too bad, it should come out with a few screws, and plugs in the back bring the speed sensor output (or speedo cable, if that's what is in the 90) and power for the lights and other instruments.

Sluggish leaving stop lights: how long has it been since you replaced the spark plugs, cap, and rotor?

Vibration: could be the Ujoints. Ever replaced them?

its an auto no idea how many miles it has speedo stopped at 103k whick i know isnt right but runs fine no problems with cap and rotor and no wandering on th highways it used to then i replaced the steering box none of that anymore it also did the woble of death i changed rims and tires and it stopped and the fluid is a nice red no flakes no burnt smell to it and another issue i noticed is she never warms up to 210 and the heat never really gets hot its like my thermostat is stuck open cause she never gopes up past 120 degrees.

Trans fluid color might or might not make a difference. If you don't know how many miles are on it, and haven't changed the fluid, guess what? It's time.

Never warms up. Have you replaced the thermostat?

When you say, "no problems with cap and rotor", have they been replaced?
