What kind of engine does a Ford Mustang have?
The 3.7 V6 from Ford has powered many flagship vehicles from both Ford and Mazda. In the 2011 Ford Mustang, the 3.7L V6 was the first engine ever to accomplish 300+hp and 30+mpg. It’s a good blend of performance and efficiency. However, no engine is perfect and this applies the the Duratec 37.
How can I tell if my spark plugs are misfiring?
If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0303 code would tell you cylinder number 3 is misfiring. Unfortunately, a P0300 doesn’t tell you specifically which cylinder (s) is misfiring, nor why. So my first plan of attack was to change the spark plugs.
What’s the firing order on a 3.7L Mustang?
Now you can pull the manifold off the car. The cylinder firing order for the 3.7L Mustang is 1-2-3 on the passenger side and 4-5-6 on the drivers side. The firing order is 1-4-2-5-3-6.
