The Ford 7.3 gas v8 engine is new for 2020.
There have been a few problems like:
- spark plug wires misfires
- stuck lifters
- knocking and power loss
- poor mileage
- Engine Misfire – If your engine is misfiring, you may notice a rough idle or a loss of power. This can be caused by a variety of issues, such as faulty spark plugs or ignition coils. Try replacing the spark plugs and coils to see if that resolves the issue.
- Rough Shifting – If you’re experiencing rough shifting or slipping transmission, it could be due to a malfunctioning torque converter. Try changing the transmission fluid and filter, and if that doesn’t work, consider replacing the torque converter.
- Stalling – If your engine is stalling or shutting off, it could be due to a faulty fuel pump or clogged fuel filter. Try replacing the fuel filter and checking the fuel pressure to see if that solves the issue.
- Overheating – If your engine is overheating, it could be due to a malfunctioning thermostat, water pump, or radiator. Check the thermostat and water pump for proper function and consider replacing the radiator if it’s clogged or damaged.
- Poor Fuel Economy – If your fuel economy has decreased significantly, it could be due to a variety of issues, such as a clogged air filter, worn spark plugs, or a faulty oxygen sensor. Try replacing the air filter and spark plugs and consider replacing the oxygen sensor if it’s not working properly.
