13 Reasons Your Car Loses Power Due To Misfire When Accelerating (Don't IGNORE!)
When your car loses power while driving or accelerating, it can be incredibly frustrating. In this in-depth video, I'll explain the 13 most common causes of car acceleration problems so you can get your vehicle running smoothly again.
Here are the key troubleshooting steps to fix sluggish car acceleration:
Fuel system components - Clogged fuel filters, failing fuel pumps, dirty injectors can restrict vital fuel flow under acceleration when the engine needs it most.
Air supply issues - A blocked air filter or intake leaks throws off the air-fuel ratio, undermining combustion.
Ignition system problems - Faulty spark plugs and bad ignition coils prevent proper firing of the cylinders.
Sensor failures - Malfunctioning camshaft, crankshaft, mass airflow (MAF), and oxygen sensors send incorrect data to the engine computer leading to timing issues, reduced power mode, and more.
Exhaust restrictions - Catalytic converter blockage and stuck Exhaust Gas Recirculation (EGR) valves cause damaging backpressure, choking the engine.
Compression loss - Worn piston rings, leaking head gaskets, faulty valves reduce cylinder compression essential for generating power.
In addition, a PCM reset can help restore lost car acceleration by recalibrating the engine control module. Don't forget to read a detailed guide on troubleshooting car acceleration problems from the link below:

    For example, if there was a poor O2 sensor reading due to excessive soot in the chamber, and it’s suggested that cleaning the sensor would solve the problem and let's say that it would do the job, would it be okay to also perform decarbonization to address the excessive soot and other particles as well? Should the decarbonization be done before or after cleaning the sensor, and would it be necessary to clean the sensor again after decarbonization?

    I only have a p0744 code which is for my torque converter. only signs I noticed is that I get low fuel mpg I have slight slipping sometimes and my car at 40mph is at 3,500rpm. At 45-60 mph my rpm’s are at a constant 4,500-6,000 rpm’s. Can I just fix my torque converter? Or do I have to replace my tranny? Which are very hard to find for my 1999 Nissan Sentra.
