I have a 2000 Toyato Avalon. The engine was replaced and now doesn't want to excellerate when the gas paddel is pressed. Once I start letting up off the gas paddle it will try to pick up some and when I'm going up hill it looses a lot of power. What could be the cause of this?
who replaced the engine? You should ask them- if they charged you money, they should make the thing run- good luck-
