Momentary loss of accleration
Have 2002 elantra sedan. has 105,000 miles on it. Had to replace transmission two weeks ago. Check engine light on . Told its oxygen sensor. When driving engine suddenly has no pick up and feels like it is going to stall. This happens within the first couple of minutes of driving. That last for about thirty seconds and then engine starts to pick up again and I can accelerate.
While it is happening even If I press the gas pedal engine feels like it is just flirting with no acceleration. Put bottle of cataclean in gas tank. Was told that make clean catalytic and clear sensors.
Any ideas on why I would get that loss of power and no acceleration. Only last for about thirty seconds but nerve racking when trying to get on highway or cross a heavy traffic street.
