I have a lot of problems with this car that I bought yesterday. It idles rough, but when I accelerate the problem goes away. It has trouble starting when the engine is cold. The coolant fan runs all the time. The A/C lines freeze up. And finally the hot air blows room temp air. It is a 1999 ford escort zx2 2.0 automatic. I replaced the spark plugs and wires, air filter, and fuel filter. Please any ideas will help
