    Are there any problems with a 7.3 liter diesel engine?
    
    The legendary 7.3 Power Stroke Diesel engine, when properly maintained can provide years of trouble free service. However there are several common problems that can develop over time. Generally speaking these can all be resolved relatively easily. Listed below are 9 common problems of the 7.3 Liter Power Stroke Diesel engine.
    
    What causes a 7.3 power stroke engine to die?
    
    Keep a spare in your glove box. Under Valve Cover Harness (UVCH) Connectors are another common fault on the 7.3 Power Stroke. When these come loose or get shorted they can cause rough running conditions to the point where the truck sounds like it has 17* timing and it lopes bad and will often die and sputter.
    
    How long does a Ford 7.3 Powerstroke last?
    
    Nonetheless, the 7.3 PowerStroke has a B50 life of roughly 350,000 miles. In other words – about 50% of these 7.3L engines last longer than 350,000 miles. That’s pretty respectable even among diesel engines that are known to outlast gasoline engines. Ford 7.3L diesels are strong internally and have what it takes to last.

    Overall, the 7.3 Power Stroke is a reliable engine. It has its fair share of common issues, however they’re pretty minor problems in the grand scheme. Ford 7.3L diesels are also getting pretty old. As such, most potential failures are fair game given the age and mileage.
    
    What happens when your check engine light goes off?
    
    A loose gas cap sends an error message to the car’s computer, reporting a leak in the vapor recovery system, which is one aspect of a car’s emissions system. If the fuel cap is loose, tighten it and continue driving. Even so, it will take some time for the light to go off, he says.
    
    Can a loose gas cap cause check engine light to come on?
    
    Some vehicle models – including the Honda CR-V – have a separate fuel cap warning indicator on the dash. Either way, if the issue is a loose gas cap, even after fixing it, you may need to drive for about 50 to 100 miles (80 to 160 km) before the check engine light resets.
    
    What does the yellow check engine light really mean?
    
    On some cars, a yellow check engine light means investigate the problem and a red one means stop right now. Try tightening your gas cap. This can often solve the problem. Keep in mind that it may take several trips before the light resets. Some vehicles have a separate indicator that warns of a loose gas cap. Reduce speed and load.
    
    It depends on the severity of the issue. If it’s a minor issue, such as a loose gas cap, it should be safe to drive. If you notice a difference in the performance of the vehicle, it could be an indication of a more serious problem and it’s best to err on the side of caution. Reduce your speed and take the vehicle to a mechanic as soon as possible.
