Common 5.0 Coyote Engine Problems In 2023(All You Need To Know Fix Them)

Having 5.0 Coyote engine problems but can’t seem to find a great way to fix those annoying issues?

There’s no need to panic. We’re here to teach you how to fix the most common problems for the 5.0 Coyote engine.

If you’re a car enthusiast, you probably know how much of a beast the 5.0 Coyote engine is.

Over the years, Ford has made some significant changes to the Coyote engine to make it even better. And they’ve certainly done a great job.

However, the Coyote Engine does experience some problems.

In this guide, we’ll cover the significant issues this engine experiences and how you can fix them on your own.


DIY Guide: 5.0 Coyote Engine Most Common Problems And How You Can Fix Them

If your engine has had a hard life, don’t worry. Sometimes merely changing the oil is enough to take care of the problem.

Here, we’ll cover the most common symptoms that could cause the 5.0 Coyote engine to malfunction.

We will also show you how you can fix those issues on your own, which you can find at the very bottom of each explanation.

Without any further ado, here are the most common problems the 5.0 Coyote Engine experiences:

1. Rough Idle

Did you recently notice an RPM drop after 27k miles? If so, you probably have a faulty fuel pressure sensor.

A damaged fuel pressure makes the 5.0 Coyote engine malfunction, which results in rough idle.

For example, if you’re driving at about 50 MPH, the rpm will slowly decrease, and sometimes after a few seconds, it goes back to normal.

This problem does not happen as often, but it wouldn’t hurt to check on the fuel pressure sensor to ensure it is the culprit.

If that is the culprit for the rough idle, you don’t have to worry too much about it as replacing the fuel pressure sensor is not as expensive as getting a new engine.

To fix the rough idle, you need to replace the fuel pressure sensor as soon as possible.

If this problem keeps ongoing, you could damage the engine even further.

To replace the fuel pressure sensor on your own, follow the steps down below:

  • First and foremost, you want to pop the hood. From there, you want to remove the air intake tube. Use a screwdriver to unscrew all the screws holding the intake tube together.
  • Then proceed to remove the air intake tube and put it to the side. Disconnect the mass airflow sensor. Now remove the cover.
  • You should have access to the fuel pressure sensor. If you still can’t find it, it is on the driver’s side all the way to the back. But now, you want to depressurize the fuel system.
  • Open the fuel tank and then remove the cap. Then open the fuse box and find the K5 and disconnect the K5 ASD.
  • Next, hop in the truck and turn on the engine. Once again, head over to the engine. You want to disconnect the negative terminal. Disconnecting the negative terminal is crucial if you’re going to work safely on the truck
  • Remove the tab of the fuel pressure sensor by pushing it down. Once you have pulled the tabs, the sensor should come right off. There is an adapter on the back that holds the sensor; you want to remove that.
  • Use a flathead screwdriver and try to get it inside the line, twist it around and pull out the fuel pressure sensor. Now it’s time to put the new sensor in place.
  • Next, you need to put everything back together

And that’s how you can replace the fuel pressure sensor on your own. If you’d rather watch a video, here is an excellent tutorial on how you can replace the sensor:

2. Stalling Issue

One of the most common Ford Coyote engine problems is a vehicle that won’t stop stalling.

If you’ve noticed a constant loss of power as you drive, you probably have a dirty throttle body.

If you haven’t cleaned the throttle body in a while, the dirt will cause the engine to act up. The check engine light will come and, and the car won’t start.

Sometimes, this problem might not be as persistent. For instance, the problem might go away for a while just to come back a month later.

There are many reasons why this could happen, such as a bad battery causing the engine to malfunction. However, we suggest checking the throttle body.

If you’re in a similar situation, consider checking the throttle body to make sure it is the culprit behind all this mess.

Here is how you can clean the throttle body of your truck:

  • Pop the hood and disconnect the battery. Then take off the air tube and disconnect the mass airflow sensor.
  • Next, you want to disconnect the PCV. Then remove all the 10mm bolts that hold the air cleaner box. Now pull out the air cleaner box.
  • Here, you want to remove the bolts from the throttle body. Like before, there are four bolts you need to remove. The back bolts are somewhat hard to remove since you can’t see them. Before pulling out the throttle body, you need to remove the electrical connectors.
  • Use throttle body cleaner and spray it on the inside of the throttle body. Now use a toothbrush and work your way through it until you have cleaned the throttle body.
  • Make sure to remove all the gunk inside. Spray as much throttle body cleaner as needed. Then put the throttle body back on the base.
  • Reconnect all the electrical connectors you took off earlier. Put all the bolts back in. Make sure to tighten them. From there, you need to put everything back on.

Now that you have cleaned the throttle body, the stalling issue should be long gone.

3. Damaged Spark Plugs

What are some of the most common 5.0 Coyote engine common problems?

Another culprit that could cause the engine to malfunction is a damaged spark plug.

Finding out whether the spark plugs are not working anymore can be somewhat easy.

Many symptoms could suggest the spark plugs are not working anymore.

If you believe the spark plugs are damaged, here is a list of symptoms you could watch out for:

  • Misfire under load – pay attention to how the engine sounds when it is running. If you hear a rattling sound, then it’s safe to assume the spark plugs went bad
  • Low gas mileage—low gas mileage is typically caused by damaged spark plugs. If you keep on driving like this, the engine will perform even worse
  • Rough idling—if the vehicle feels rough every time you turn on the engine, there is a high chance that the spark plugs need to be replaced

If you notice any of the symptoms mentioned above, it’s safe to assume the spark plugs went bad.

Consider replacing the sparks plugs to fix any of the problems we just went through. That’s how you can get rid of those problems.

If you want to replace the spark plugs on your own without taking the truck to the mechanic, here is how you can do this on your own:

  • Pop the hood and find the engine cover. Remove all the bolts to remove the cover.
  • Once you have removed the cover, you will have to take off the air tube assembly. Flip the lever and unplug the connector that holds the air tube assembly. Use an 8mm socket to loosen the clamp on the air tube.
  • Pull all the hoses off. And right underneath the air tube, there is a mass airflow sensor that you also want to disconnect.
  • Next, you want to get the steering reservoir out of your way. To do this, you must remove three bolts. Remove the bracket next to the steering reservoir, then remove all the coil packs.
  • Use a mac double swivel spark plug to remove the damaged spark plugs. Once again, use the double swivel spark plug, but this time you need to use it to put the new spark plugs in place.
  • Next, you want to tighten the spark plugs. And finally, you need to put everything back in place.

And that’s it for the installation process. If you’ve ever replaced spark plugs before on other vehicles, you’ll notice that replacing spark plugs on the Ford F-150 takes a lot more time.

4. Shake While Idling

What could suggest Ford F150 5.0 Coyote engine problems? If the car is shaking while idling, you need to change the oil.

If you wait too much time to change the oil, the oil will turn into nasty sludge.

If that were to happen, the engine wouldn’t work as before. Furthermore, things could get pretty messy if this keeps ongoing.

The 5.0 Coyote engine is one of the best on the market; that engine is made to last for a very long time.

Most of the time, when the engine fails, you have to change the oil. Oil is relatively cheap. You would be surprised by how much it would help if you changed the oil regularly.

To change the oil of your truck on your own, follow these steps:

  • Jack up the truck and crawl under the vehicle. Then place a container underneath the drain pan so the oil won’t cause a mess.
  • Remove the bolt from the drain pan using a 16mm socket. Now pull it out and watch as it drains all the oil inside. Let it drain. Put the bolt back in once all the oil has drained out.
  • Next, place the container under the little opening of the vehicle. That’s where all the oil will come from once you remove the oil filter. Now locate the oil filter and get it off.
  • Put some oil inside the new oil filter. Do not fill it up. You want to go halfway. If you fill it up, it’ll spill a little bit as put it back in. Then put the new oil filter back in. Be careful, as you might make a mess
  • Pop the hood. Now locate the oil cap. Remove the oil cap and pour in the new oil until it’s at its recommended level.

See? It’s not as hard as it might seem. And by changing the oil on your own, you saved lots of money.

5. Damaged Ignition Coil

A faulty ignition coil will not give enough power to the spark, which causes the engine to perform poorly when driving the vehicle.

If you believe the ignition coil went bad, here is a list of symptoms that suggest the ignition coil must be replaced:

  • The car shakes at idle
  • Misfiring
  • Low gas mileage
  • Lack of power

If you want to make sure the ignition coil is indeed responsible, pop the vehicle’s hood, and take a look at the ignition coil.

Also, If the ignition coil looks worn out, you must replace it as soon as possible.

Follow these steps to replace the ignition coil on your own:

  • Pop the hood of the truck. Once you gain access to all the parts of the vehicle, you should see the oil cap. You want to remove it.
  • Now proceed to remove the cover. Disconnect the high-pressure fuel pump connector and remove the lube.
  • Then disconnect the bottom hose. Currently, there is this one wire tie that is holding all the vacuum lines. You want to remove the wire tie to free the vacuum lines
  • By now, you should have access to all the coils. Here, you want to remove the connector. We suggest using a flat head screwdriver to remove the connector successfully. Use an 8mm socket to remove the bolt.
  • Now slide the new ignition coil into position. Put the bolt back in and then apply pressure to tighten it. Put everything back on
