What engine does your Firebird have? Attach a computer scanner and retrieve the fault codes from the engine. This should tell you where the problem lies. If it's an ignition problem, it should also tell you which cylinder has the problem.

2004 Sebring 2.7 runs good till heats up then will die. like fuel starved. the oil light starts to come on at 1500rpms then runs rough and have to keep engine rpm high.

If you need to keep your rpm above 1500 to keep the oil light from coming on, you need to have that checked RIGHT NOW. When the light comes on, oil pressure is at an absolute minimum. Check the oil level in your crankcase, and top it up if necessary. If you still get the light coming on, you may have a bad oil pump, excessive wear on bearings, or a bad oil pressure switch. Get it checked out or you are liable to blow your engine.

My 2004 ford freestar has no heat. how do I add antifreeze or check if it is the thermostat

When the engine is cool, take off the radiator cap and add fluid till full. Also add coolant to the overflow tank if needed
To check the thermostat, leave the radiator cap off, turn heater controls to high heat, and start the engine and run it till at operating temperature (this is to remove air from the system.) Coolant level should drop a bit when the thermostat opens, so you may need to add more. Replace rad. cap when engine is warmed up.
The only way the thermostat would cause no heat is if it were stuck open. So feel the upper radiator hose as the engine warms up. It will be cold or cool till engine starts to warm up-should take about 10-15 minutes, and then the thermostat should start opening, and the upper hose will start getting hot. If the engine takes a long time to warm up, like 30 minutes, the thermostat may be stuck open, needing replacement. If all seems good, check the actuator doors (temperature blend door) on the heater case. The doors have to open properly to let air from the blower motor to pass across the heater core, and then out the vents.
Good luck. If the coolant level was low, that was likely the problem.

When my corolla is cold it starts fine. I can drive for about a 1/2 mile and then it quits and will not start. I let it sit for awhile and it will start again but not run for very long. So it seems to be...

Is there any kind of check engine light on, or emissions light on? Sometimes when the ignition coils heat up they will short out and stop working, and after they cool down they will work again only till they heat up, then they will stop. If this doesn't help i would need more information to better diagnose whats wrong. Thanks, good luck, Bob

Change your gearbox oil, and clean out the oil strainer.
Should help.

( On some models, you have to remove the gearbox oil pan to clean the strainer )

Service engine light ---on and off, and on and off

I disconnected the line and blew them out. I found nothing in the lines. There were no leaks or clogs so I replaced the power steering pump, reconnected the lines, filled with fluid and primed. Seems to be as good as new now. Did not mind the work although tight in some spots but the price for a new pump, over $200.
