My 2004 Honda Accord Brake and TCS light stays on.
I will assume you know there is a button on the dash to turn the TCS on and off. Make sure that button has not been pushed. The brake light can be on due to worn brake pads or low fluid level. If the TCS is not turned off then I suggest you take the car to a trusted mechanic or to your local Honda dealer and have it looked at. It takes skill, knowledge, and the proper tools to diagnose this type problem. It can be many things including a sensor, and you can spend lots of money guessing. Spend the money to have it repaired by someone who knows what they are doing. You will be money ahead and have it done right the first time.

What does the TCS Off button do?
TCS stands for Traction Control System.
The traction control system works in conjunction with your Antilock Brake System (ABS) and your Engine Control Module (ECM) or Powertrain Control Module (PCM) or Electronic Control Unit (ECU) (Note that ECM, ECU, and PCM all mean the computer that controls your engine, depending on make.)
Anyway, the traction control system can apply one or more of the brakes and control engine RPM in the event that a wheel slip has been detected by the traction control system.
Pushing the TCS button on most models will light a lamp in the instrument cluster that usually says "Trac Off" Pressing it a second time will turn this light back off.
When the "Trac Off" light is illuminated, the Traction Control System is disabled and will not work in the event of a wheel slip.
Also note that when the Traction Control System is working and a wheel slip is detected, The Traction Control Module will usually illuminate a light that says "Trac" as it is taking control of your brakes and engine. It can feel really strange when this occurs and some people think that their transmission is slipping or that their engine has a misfire problem.
The chances are that if it occurred on wet, slippery pavement, the Traction Control System may have just saved your life.
If this is happening on dry pavement and normal driving conditions (starting, stopping, or turning), there may be a problem with the system. "False Traction Control" can happen just like a bad wheel sensor causing "False Antilock Mode".
Also check your Owners Manual for more specific information pertaining to your particular vehicle.

How do a repair a reduce to slow mph on highway
Your ECM (car's brain) has reduced your car to Limp Mode. You'll need a Fault Code Reader and list of fault codes for your vehicle to diagnose the problems. Fault code readers aren't expensive and Haynes makes inexpensive DIY manuals for your vehicle. Could be the EGR, PCV valve, TPS, or Oxygen Sensors. Each of these has a separate fault code... please check a fault code reader and verify the fault against the list in Emission Controls list in the Haynes manual. This will narrow it down for you.

When u start the car it dies out why?
There are many issues that can cause this. Most common are fouled spark plugs, clogged fuel injectors, bad Oxygen sensors, PCV valve stuck, broken or disconnected vacuum lines. DFENSO plugs and O2 sensors will fix those problems. Vacuum lines require a thorough inspection using the diagram inside the hood; tracing every line and inspecting for cracks. Your fuel injectors are also DENSO, they can be cleaned using specialized machines... a Bosch service center has the machine to clean them and test the spray pattern for proper flow. Vacuum lines are easy to replace and the PCV valve just screws on. If these don't work, then you have an ECU problem. Rebuilt ones are available on line for around $100.

Check Engine Light Comes on Intermittently
The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.
