Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

First it overheated, would go into the red, then back down about halfway, and up again, on highway and city(dummy me i didnt pull over), it shut off about a mile from my destination, started back up and finished trip. I replaced the thermostat and coolant, drove it round the block and still got hot. Then i took out the thermo and it runs around 120degrees, but it runs real rough, i was thinkin i might have blown one head gasket, i get little plums of smoke from under the exhaust manifold on the front of the engine, also very white exhaust, and smell of coolant. When i first got the car coolant would come out of the pressure sensor and u could smell it. Im thinkin i prolly need to replace my uim, and lim. I would greatly appreaciate any suggestions, im not currently drivin it i parked it, o and my brakes decided to take a dive, i have no pedal pressure, and when its to the floor its like if i were to barely press on the pedal of a normal car. UGH!!
 


Unfortunately this sounds like an Intake Gasket failure. This is a common problem with any GM V6 engines from 1995 to 2006. If you can smell the coolant I'm guessing its in the advanced stages and would cost a hefty amount to repair (around $1000). Depending on the trade-in value of your car you may want to weigh the pros and cons of either repairing the damage or just buying a new car. Good luck.
 
Well ya its gonna run like crap if you have coolant leaking into the engine....Do you have coolant in your oil or a milky substance under your oil cap??? Gimme some symptoms and Ill letcha know which it is
