2003 Ford Explorer O/D off Light flashing?

I know that the O/D means over drive and since it's flashing, it's because there's something actually wrong with it. I'm a broke college student and this vehicle is all I have. I can't really afford a new vehicle. I have an appointment on Wednesday.

I was just wondering what could the problem be? How much will it cost me? And could it be something as simple as transmission fluid being low?

Engine swap for Ford Explorer?

I have an 01 Explorer Sport Trac with the 4.0 V6 with 235k+ miles. So far, the engine has held up quite well, and the vehicle overall is still in good shape. But I realize it probably doesn't have much longer. I doubt I would be able to get anything if I were to sell it. So the idea of an engine swap came to mind. I was looking at the 5.0 that came in the Explorer at the time only has an additional 5/10 HP. Is there an engine that would be sufficient for a swap? I don't know if a 4.6 or 5.0, or possibly something else that I could look into?

1996 Ford Explorer - P0401: Is it my DPFE sensor?

1996 Ford Explorer. 4.0L V6, 4WD.

I'm got a P0401 code (EGR Low Flow) and will obviously will not pass emissions because of it.

I bought a hand operated vacuum pump and applied 5 pounds (maybe inches) of pressure through the EGR valve and it stumbled quite a bit. This means that my valve is working and that the passages are clear straight to the throttle body.

My only bet is the DPFE sensor (aka EGR pressure sensor), as I have read that it is usually these that go bad and not the EGR system itself.

Why does my 99' Ford Explorer go through so much radiator fluid?

Hi and thanks for your time, I have a 1999 Ford Explorer Sport with a V6 SOHC. I got it about 2 months ago and it was running great! So I topped off all the fluids and noticed it used a full gallon of 50/50 antifreeze and still needed more, so I filled it up with water. The next day I went to check on it by pouring more water and it used up a whole gallon of water. Now I find myself filling it up with water at least 2 times a day. The weird thing is, when I got to take off the radiator cap, no steam comes out even with a hot engine! Do I have a problem with my head gaskets? It seems to run fine!

Is my MAF sensor good or bad?

I cleaned my throttle body, throttle position sensor, MAF, and changed my spark plugs a couple weeks ago in an attempt to fix some idle issues (car died at a stop/slowing down but would start back up and run fine). Fixed the idle issue but now i'm having issues with my air intake not getting enough air to the engine. Best way to describe it is that when i'm accelerating, it takes the engine time to catch up. I'm trying to narrow down the problems I'm having with my air intake. I've got check engine codes P0506, P0102, P0113, P2106. With my car running, I disconnected the MAF sensor, when in park there isn't much difference and will stay on. However, when I drive it the "Engine Failsafe Mode"(or as some call it, "limp mode") message pops up.

My car is a 2004 Ford Explorer Eddie Bauer 4.6L. If it means something, I did clean my throttle position sensor by accident (with throttle/air intake cleaner thinking it was my IAC valve, which I found out I don't have because I have a fly-by-wire/throttle-by-wire system. Considering the fact that this happened after I messed with the intake, I can only assume I was a little rough somewhere and messed up something on the intake. It runs, but it just takes it a little bit to match the speed (once again, like not enough air is getting to it)
