Sometime in the summer my engine light started up without any 'real' noticeable problems but with time, I've tried several things overall to fix the problem. When a mechanic scanned my car, they said that it was a problem with the cooling system, so I switched the thermostat (for a new factory one) and the sensor that accompanies it. This helped slightly, and for a while, it was better, but again the problem has returned. THe heater works quite well, and the vehicle works well the majority of the time. Since it's winter in Canada, it has to withstand -50 degree (celcius) weather, so sometimes when I start it, it'll idle around 3000-4000 rpms. Does anyone have a similar problem? Help?

You just cant go disabling things the light will stay on. From what I have seen usually the coolant temp sensor sets that code. What the code is saying is there is too great of a difference between the transmission temp verus the coolant temp after a certain amount of running.

I had a diagnostic done. This is my wife's car now. I do not want to leave her and the baby stranded. These are the readings the diagnostic gave:
Open or short circuit condition
Poor electrical connection
Faulty EVAP vent valve
Are any of these costly? May I repair any of these myself? Could any of these leave my wife stranded?

They sound related. Chances are the connection the evap valve is loose or corroded causing the problem, or there is a broken or damaged wire to it. I would recommend having it looked at by a mechanic to determine the exact cause. Honestly, it shouldn't be too much money to repair, but make sure to get a quote prior to the repair.

Also, if I am correct, this problem shouldn't leave her stranded. It will, however, cause the vehicle to fail emissions inspection if you live in an area that requires it.

I just recieved a check engine light and took the card to autozone to have them perform a check engine test. The codes that came back were P0171 and P0170? The most common problems were Syst too lean, faulty EVAP MAF, Ignition misfire repair, Blocked injectors, Ignition syst fault, fuel syst fault?

Lean fuel condition could be caused by one of the following below:

1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor.

The first thing you need to do is have the car scanned for codes let me know the exact code numbers you have not code descriptions. Without them cant tell you much.

2004 Hyundai Tiburon 6 cyl Front Wheel Drive Automatic 60K mi miles

Today, my 2004 Hyundai Tiburon had the check engine light come on. I couldn't help but notice it happened at the same time that my rear windshield wiper makes a clicking noise when turned on. The wiper still works fine, but right when engaged it makes one loud click. Any ideas?

What I need you to do is have the computer scanned. If the check engine light is on, there is a trouble code stored in the computer that will help identify where the problem is coming from. Have that done and let me know what you find. Note: Most nationally recognized parts stores will scan the computer for free.
