Bad wiring connection somewhere. Finding it is the problem, because it could be anywhere. Look underneath for scuffed connectors.https://www.google.com/search?q=1998+Ford+Mustang+V6+automatic.+When+hitting+a+bump+the+radio+turns+off..

this diagram is from the Factory service manual, the coil pack may be over the passenger valve cover on your year, the orientation of the coil leads is the same though.

Hi there:Misfire is a common driveability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25 percent of the engine power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle.Basically, it's one of three things: loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad spark plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.Lean misfire can occur when the air/fuel mixture is too lean (not enough gasoline in the mixture) to burn. This can be caused by a dirty, clogged or inoperative fuel injector; air leaks; or low fuel pressure because of a weak pump, restricted filter or leaky pressure regulator. Low fuel pressure would affect all cylinders rather than an individual cylinder, as would most air leaks. A leaky EGR valve can also have the same effect as an air leak. In fact, if a vehicle has one or more misfire codes and a P0401 EGR code, the fault is likely carbon buildup under the EGR valve.Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited. The most likely causes here are a leaky (burned) exhaust valve or a blown head gasket. If two adjacent cylinders are misfiring, it's likely the head gasket between them has failed. Also, if an engine is overheating or losing coolant, it's likely the head gasket is the culprit.Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load or operating conditions. They seem to occur for no apparent reason. The engine may only misfire and run rough when cold but then smooth out as it warms up. Or, it may start and idle fine but then misfire or hesitate when it comes under load. Also, it may run fine most of the time but suddenly misfire or cut out for no apparent reason.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

Have you checked for spark at the plugs and the fuel pressure ? Can you hear the pump run for 3 seconds when you turn the key on ?

I would try looking on ebay. You can purchase inexpensive parts on there. Mike. Rate 100% please.

In the IP fuse panel #6 fuse is a 15A and #17 fuse is a 30A.

Check your battery to make sure it has enough power and cranking amps to turn that starter and flywheel.  Make sure that your cables are good and move them around to see if that helps. Sometimes those cables can break and corrode inside the outer covering and you can't see it which makes it hard to diagnose. Clean your battery posts and cables. Also another thing you can try is starting in neutral or rolling your car back a few feet to allow it release some tension and hopefully free up allowing it to crank over easier. When you replaced the starter did you make sure to slide it in place and tighten it down good? Did you use shims to allow proper clearance room?...

You don't , you need the dealer or mobile lock smith program new key's .

Your readiness test will allow your PC to reset & if u are going to get a check engine light that's going to come that's the time it will come on, after the "readiness road test" Take it out & dive high & low speeds. If that light is to come on it will.

In my opinion they definitely should have checked them the first time. Some freezer plugs aren't that difficult to change. I have also seen people just slap some high temp sealant on them to repair the holes. More commonly they just rust out and they probably should have seen that when they were looking for licks the first time.

Have you replaced the broken hose? The bad part can cause the other codes to appear so fix what you know is bad, disconnect the negative battery cable for 10 minutes afterwards and then start it up and see what happens. All you need to do with the codes are to put each one in the search bar and search for ford code p1443, ford code p0136, and ford code p0141. But do that after you fix the obvious problem.

I suspect the fuel injection is poor. Try to check the fuel pump, there maybe no much pressure from the pump.

Depending the style. Go to google. type in 1998 ford mustang fuse box diagram and search for images. Locate the closest one to your fuse box and look on label for "fan" I’m happy to help further over the phone at https://www.6ya.com/expert/zelio_00a80ed57645ccbf

Oxygen sensors may be reading false rich making it go too lean .

If the antitheft light is blinking then the pcm is not getting a signal from the PATS transponder. The Check transponder ring, wiring, PCM fuse in under the hood fuse panel, and lastly pcm. Good luck.
