when I step on the gas in my car it hesitates. If I ease in to the gas it runs fine. When I am driving it, it hesitates until a certain rpm , but then it shifts and starts all over again. I just change the O2 sensor before the catalytic converter because the engine light was on, and I thought that would fix the hesitation. When the check engine light came on, that is about the same time it started to hesitate.
