My car started to lose power while accelerating especially at freeway speeds it keeps trying to kick into overdrive and has a hard time going uphill and accelerating also makes a louder engine noise when doing this
My car has 140000 miles.
My car has an automatic transmission.
Loss of power on acceleration can be due to plugged fuel injectors, faulty oxygen sensors, fuel pump and/or filter, vacuum leaks including that caused by a faulty EGR system, ignition system malfunctions, bad valve timing if the timing belt or chain is worn or skipped, blocked exhaust (e.g., catalytic converter fails or becomes clogged), a faulty airflow sensor or throttle position sensor, and so forth. To pinpoint the exact cause will require an engine loss of power diagnostic. If you request that diagnostic, the certified mechanic will get this resolved for you.
