What do the wire in the middle goes to any help because my car keeps shutting of after 30 min of driving -97 mustang gt


You have to realize, that is your alternator. Your alternator only charges the battery. If your battery is going dead, then I would think the alternator might be the problem. But if it is charging, then it is doing its job. You need to find out what you are loosing when the engine dies. I would start with putting a fuel pressure gauge on the fuel rail so you can monitor the pressure when the engine is running and make sure you have over 40lbs of pressure and let the engine run until it dies. Make sure you have good pressure up to and a bit after it dies. If you have good pressure then go to the ignition system and make sure you have good spark and see if that is what you loose when it dies. Same thing with the injectors, you will need what is called a noid light to see the injector pulses.

My 2000 malibu chugs while going down highway 5 miles an hour


If you have done basic tune up stuff, I would check fuel pressure with gauge installed and running down the highway. Other possibles are bad ignition module, loose wire somewhere in coil circuit, bad fuel pump, filter, many others.

Car runs perfect then starts missing real bad then stalls


Not unusual for fuel pumps to begin to fail once they are heated up from running. First thing in the morning pump is cool, then as you drive, it heats up and begins to lose pressure. After sitting a 1/2hr-1hr, it may start again and run fine for a short time and start to act up again. Had similar problem and found good fuel pressure when tank and pump cool, but lost pressure once vehicle driven a distance and pump heated up. The hotter the weather, the shorter the distance I could drive. If you can somehow set it up to have fuel pressure checked when it starts to act up, that would certainly help confirm if fuel pressure is the culprit.

My car is over heating when im going down the hwy


May have head gasket leak. If so will be loosing water, possibly quite slowly. At highway speeds cylinder pressure is higher and so gasket leak more likely. Means gasket damage or loose cylinder head. Can be checked by mechanic. (pressure test and cylinder head bolt tension test)
Less likely alternatives, the spark timing is too advanced or the fuel too poor.

Mazda Tribute 2002 engine cuts out randomly


I had a Mazda 626 with a similar problem, the car seemed to 'shut down' with no warning, even at highway speeds, as if I just turned the ignition key to 'Off'; After trying to fix it unsuccessfully by replacing several electrical parts, the problem was found to be a defective ignition switch, it was replaced and the problem went away.

Manual heating system with automatic trans. 7.3 L Diesel, 45k miles


it may be your thermostat, the gauge on the dash is a dummy gauge, there is only three positions that it sees, dead cold, operating temp, and hot, so even though the needle looks fine it just means it s closer to operating temp then it is to cold,
