What causes a Ford truck to lose power?
A weak or failed ignition coil is another potential source of a loss of engine power. Ford Modular engines are well known to have issues with the coil on plug systems. Coils get weak with age and misfire under load. This is often misdiagnosed as torque converter shudder.
What causes an erratic shift in a car?
In today’s computer-controlled transmissions, an erratic shift could also be due to a bad sensor or shift solenoid. These types of problems can often be checked using a transmission or factory scan tool that can check pressures and solenoid operation when plugged into your car..

How can I tell if my car is losing power?
Many of the issues it detects relate to power loss — including problems with the catalytic converter, the mass airflow sensor, the O 2 sensor or the spark plug wires. More important, small problems often hint at larger ones [sources: Consumer Reports; Reed ].
What to do if your truck has no power?
Truck has no power and bogges down down when given throttle. I have changed the plugs, distributor cap and rotor. Still did not fix the problem. Replaced the throttle position sensor and thought I found the problem but still bogges down.

If these impurities were to get into the engine, they could cause severe damage. However, air filters tend to get clogged after they’ve been used for a while. Once an air filter gets clogged, it will limit the amount of air that can get into the internal combustion chamber.
