Ford F-150 owners, especially those without a Raptor model, might come across a common problem known as the misfire/shutter problem. In this article, we will be discussing the specific issue related to the Ford 6.2L engine and provide a step-by-step guide on how to fix it. If you own a 2011 or later gas-powered F-150, this information is crucial for you. Let’s dive into the details and remedies for this problem.

Introduction to the Ford 6.2L Engine

The Ford F-150 equipped with a 6.2L V8 engine, often referred to as the “raptor motor,” is known for its reliability and overall performance. While many F-150 owners boast about their trucks’ features such as rims, tires, and colors, the 6.2L engine has gained a positive reputation among its users. However, one problem that can arise is a misfire or shutter issue, which we will address in this article.

Symptoms of the Misfire/Shutter Problem

If you experience a sudden rough running engine or a snap-like sensation while driving your Ford F-150 with a 6.2L engine, you might be facing a misfire problem. The misfire is caused by a broken valve spring, typically occurring in the number eight cylinder, located towards the back of the engine. This broken spring causes the valve to sit open, leading to an improper firing sequence and wasted fuel. To identify this issue, you may notice a check engine light indicating a problem with cylinder eight.

Addressing the Misfire Problem

If you suspect a misfire problem, it is essential to follow the correct troubleshooting steps. Here is a step-by-step guide to help you fix the issue:

  1. Check the Spark Plugs: While changing the spark plugs may not directly solve the misfire problem, it is a good practice, especially if you haven’t replaced them in a while. Remove the old spark plugs and replace them with new ones.

  2. Inspect the Valve Cover: To locate the broken valve spring, remove the valve cover. The broken spring will be easily visible and will require a new gasket for resealing.

  3. Replace the Valve Spring: Purchase a new valve spring, which is an inexpensive fix. It is recommended to replace the valve gasket at the same time. If you are not confident in your DIY skills, taking the vehicle to a trusted mechanic will ensure a successful repair.

Cost and Difficulty of Repair

Fixing the misfire/shutter problem in the Ford 6.2L engine can be relatively affordable if you choose to do it yourself. The valve spring and gasket are inexpensive, typically costing around $10 for the spring and $3-4 for the gasket. However, the repair process can be time-consuming and requires precise steps, such as setting the engine to top dead center and pressurizing the cylinder.

If you decide to seek professional assistance, it is advisable to avoid dealership prices and find a reputable local mechanic. While the cost may vary, a fair estimate for the repair should be around $500-600, ensuring a proper fix for your truck.


The Ford 6.2L engine misfire/shutter problem is a well-known issue among F-150 owners. However, it is both manageable and fixable, either by tackling the repair yourself or seeking expert help. Following the steps outlined in this article will guide you in addressing the problem and getting your Ford F-150 running smoothly once again.

Remember, regular maintenance and early detection of any issues can help prevent major complications in the long run. Stay informed and take care of your vehicle to enjoy uninterrupted performance on the road.
