hey mike this is because the computer has set a trouble code for the emissions you can go to auto zone and ask them to scan the vehicle for you they do this for free with the hope that you will purchase the parts from them for the repairs to be made but it's not a problem if you don't so go to one or advance auto and find out what's wrong then fix it as fast as you can because your computer is in what's called open loop this is a alternate program installed on the computer to keep the vehicle running to get it to the dealer/repair shop and this is not the optimum running program & you will use a lot of fuel and possibly damage other components in the process if you keep operating in open loop O.K. so don't listen to other people who tell you that they run there car like that all the time you'll be sorry later just fix it asap!

Use a paper towel to soak up some of that fluid and try to identify what kind of fluid it is. I'm guessing it would be coolant and the problem would be you need a new water pump.

You may have a really dead battery that needs to be replace. If its sat for a long time its likely dead and a jump won't be enough. If your car has an alarm system this will also need to be reset.

Sounds like you may have a clogged EGR hose or valve. Make sure you've replace the air filter and PCV valve first as these will also have an adverse affect if they are clogged.

Well Not really sure i understand your question. But if i get the gist of it i believe the battery on your remote start may be low and Be sending a signal to your car to start. Try replacing the battery in your remote. Hope this helps.

It maybe the seatbelt connection fault as some fords don't all have an illumination on dashboard

it very well can be that depending on the severity of the ticking noise, if it sounds like its coming from the top of the engine, place your hand on it only when you first start it up and if you can feel it knocking slightly and if the noise dies away once warmed up id say its your lifter, if its a heavier knocking rather than a ticking and comes from below or bottom end of engine it may be big end bearing, not good. try putting some engine treatment through the engine oil and make sure you run it in as directions state then change the oil and filter and see if that helps :)

the speed sensor is located on the side of transmission toward the rear of the trans, is simple too replace, if you buy then new one and jack and support the vehicle look under Neath and it simple unplugs then use a crescent wrench take tork off and unscrew it. there will be little trans fluid (1tea spoon ) that will come out and that's normal on a scale of one to ten it rates 2. so not hard.

Either relay or multifunction switch. Start by swapping a relay to see if that fixes it. If so great if not then its going to be the multifunction switch
