One common problem with the F-150 is engine misfire when one cylinder starts firing erratically or not at all. Lenny from 1A Auto shared that it may not be difficult to diagnose the problem or even fix it yourself.

. Look for a crack in the enamel insulator, often lined with sooty deposits. Also inspect the rubber boot that fits into the spark plug, and its attachment to its ignition coil.

You may be able to solve this problem by replacing only one spark plug, or by replacing the ignition coil cover and not the entire ignition coil. But Lenny warned that if your truck is close to 100,000 miles, you should consider replacing all of your spark plugs at the same time.

One problem with the 2009-2014 F-150 EcoBoost engines is condensation inside the intercooler. The intercooler is the intercooler of the turbocharger mounted in front of the intercooler. Left unchecked, this problem can cause the engine to stutter or even fail when accelerating.

Ford introduced the 3.5-liter turbocharged EcoBoost engine during the 12th generation F-150. Obviously, the automaker still has a few things to do, including a buildup of condensation in the turbocharger’s intercooler.

Ford claims that this problem is inexpensive to fix: simply remove the intercooler cover plate and reinstall it on the brackets on the bottom of the unit. Although this procedure is not lengthy, you may still want to leave it to a professional. But the good news is that you won’t need to buy new parts or spend a lot of time shopping.

Turbocharger coolant leak

One of the key features of the Ford EcoBoost is its use of engine coolant to keep turbocharger temperatures low. Unfortunately, first generation EcoBoosts could suffer coolant leaks because of this. This problem can lead to increased engine temperatures and a puddle of coolant (antifreeze) leaking from the rear of the engine.

A coolant leak is often caused by the fittings that connect the intercooler lines to the rear of the turbocharger.

You can certainly diagnose this problem yourself. Simply use a flashlight to look for fluid leaks from your turbocharger. If you find a coolant leak, you’ll need to replace the turbocharger’s coolant fittings–as well as the lines they connect to–.
