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:

New Structs, new motor mounts, new sway bar links, new sway bar bushing, new lower arm control with new ball joints, new tires with balanced and re-balanced and alignment and STILL THE SAME. ----- STOP MAKING VIDEO TO MAKE PEOPLE CRAZY AND SPEND MONEY BUYING AND REPLACING PARTS FOR NOTHING.

    I went for about 2+ years with a finicky front O2 Sensor on a 2002 Solara SLE V6 1MZ-FE (MCV20). No misfire though.....It would trigger the engine warning light but reset to good on the next startup. Gas mileage did go down as I have driven this car for 22 years but not to the point of expensive repair before my 300,000 mile service. The rear O2 sensor under the car is factory still and they rarely go out. As to the recent real problem(s) was a misfire started a month ago on startup in the garage due to other factors according to my repair shop. Oldish spark plugs, bad ignition wire set, and two bad direct ignition coil. My car shook with two cylinders out I thought it could be about 9 things but in reality this was not a heavy fix. Repaired now and ready to go after the 400,000 mile mark.

This happens for a brief moment, and then the car continues to run normally. Some mechanics measured that at that moment the voltage drops to 13V. Almost all parts have been replaced (engine computer, new battery, alternator), but the problem still hasn't been resolved. I would appreciate any help if possible. Thanks in advance!
