I'm working on a 1994 Taurus with the 3.8l v6. First things first, it was owned by my uncle's ex-wife's sister. She drove it every day and began to have problems with it. She got someone who I was told has no mechanical skills to work on it. Someone else told him over the phone, without seeing the car, to put a toggle switch on "it." Nobody knows what "it" is, but now there's a toggle switch next to the dimmer on the dash that seems to do nothing.
When I went to start it, it wouldn't start. I cranked and cranked, but it wouldn't even sputter. Finally it did sputter. And it didn't start. Fast forward almost ten minutes, and I got it to start. It's coughing and barely staying alive, and as soon as I let off the gas it died, but fired right up again. After keeping it running for ages, I could let off the gas, but it idled barely fast enough to keep running. Idle picked up after a while. Greyish/white smoke came from the exhaust, so I thought it was oil, but a visual inspection of the top of the engine displayed the problem. Around the intake manifold was a small bit of water, so obviously the intake manifold leaks. I'm told it overheated at one point, so hopefully the head gaskets aren't blown.
I tried to pull the codes after running it a bit- no koeo
codes, but I got two koer
codes- 536 and 521. 536 makes sense, because the power steering is going out, according to my uncle. As for the brake on/off sensor, I don't know.
Any ideas for solutions? Part of the deal with this car is that I figure out what's wrong with it and get started on a repair, otherwise my uncle wants to haul it off as scrap metal.
Also, there's a ground wire that seems to be unplugged. It's near the hood latch next to a bunch of other wires, and it's just dangling there. I have no idea what it plugs into.
