Why is my engine losing power?
I drive a Toyota Corolla S, 2006 model which had a mileage of 106,000 kilometers. Recently I have noticed that while moving, the engine power goes down as soon as I hit the brakes and stalls. I turn off the engine and it restarts again. It happens again immediately after I touch the brakes. What could be the problem?
engine is being restricted either by fuel .timing or both. ( assuming breathing issues are not involved)diagnostic check at a garage will sort . the coming off the throttle allows correct fuelling /ignition to occur. it may pay to have car serviced at same time.
check your electrical ignition system to see if it's time for a tuneup.
Sounds like your alternator is on the frtz, or you need a newbattery. take the car to a reliable shop, & have the check it out
check for loose/dirty battery cables...2 go to advance auto or other parts store for free check of battery,alternator,,,,check engine lite on get free scan there too
