Ford 6.0L Powerstroke Misfire / Running Rough

6.0 Powerstroke Misfire

6.0 Powerstroke Misfire

Various problems can result in a rough idle or misfire in your 6.0 Powerstroke engine, including dirty fuel injectors, clogged air filters and potential exhaust system issues. While some of these problems might appear minor when they first begin, it’s critical to resolve them immediately to prevent your engine from developing more significant issues.

What Causes a Misfire in Your 6.0 Powerstroke?

Although an occasional misfire might not seem like a big deal, it’s critical to determine the cause immediately. Otherwise, your engine might shut down or refuse to start when you don’t expect it. Uneven or rough idle is one of the top symptoms of a misfiring engine.

If your engine is missing intermittently, diagnosing the problem can be challenging. Your fuel injection control module (FICM) could be the culprit, particularly if the misfiring occurs when traveling between 45 and 65 mph. 

Using a scan tool can help determine the cause of an intermittent misfire. For additional insight, navigate to the testing section at and follow the step-by-step instructions. If everything appears to be working correctly, contacting a certified technician to perform a professional diagnosis might be your best option.

6.0 Powerstroke Rough Idle Causes

Your engine’s fuel pump pulls the fuel from the tank to the injectors. When the fuel pump clogs or becomes severely dirty, the system will not get enough fuel, causing rough idle, slow acceleration, sputtering or stalling. Signs that your 6.0 Powerstroke is having idle problems include:

  • Shaking or bouncing
  • Noticeable skipping
  • Inconsistent or variable RPMs

Some of the reasons behind these problems and their potential fixes might include: 

Cause: Your fuel injectors have stiction.

Solution: Using Hot Shot’s Secret Stiction Eliminator in your engine can restore compression and cleanse your injectors. In addition, using our Diesel Extreme helps remove all internal injector deposits while cleaning the whole fuel system.


Cause: Your injectors are faulty mechanically.

Solution: You need to conduct diagnostics to test for serious injector or electrical issues.

Intermittent and Continuous Rough Idle

Intermittent Rough Idle in Your 6.0 Powerstroke Engine

Various issues could be the culprit when your engine runs rough intermittently. If your engine seems rough when cold but smooth when running warm, there’s a good chance stiction is causing the problem. Hot Shot’s Secret Stiction Eliminator can be effective in cleaning out the gumming behind this issue. Stiction Eliminator can also help if your engine runs roughly only at idle.

In addition to adding Stiction Eliminator to your engine, a dose of Diesel Extreme to your fuel tank can thoroughly clean your entire fuel system, including the cylinders and lines.


Continuous Rough Idle in Your 6.0 Powerstroke

If your engine is running rough consistently, determining the cause may be more complex. Constant spitting and sputtering regardless of temperature could be the result of a stiction issue, in which case Stiction Eliminator can help you resolve it. However, this problem could also arise from a faulty injector, which falls beyond the scope of our product.

An electrical issue like a bad spark plug or a failed sensor can produce similar effects, as can an ICP sensor malfunction. If you suspect something like this may be the case, use a scan tool to diagnose the problem.
