I own a '02 Olds Alero with the 2.2 Ecotec and i have a hesitation when you stomp on it. From a dead stop you get on it a little it has a hesitation like when the ETS activates in the snow, like it hits a dead stop, kinda like hitting the governor. It also happens when you go to pass someone, it does it worse when it is colder. I have replaced the fuel filter, sparks plugs, and the spark plug wires, i have also added fuel injector cleaner but none of this has helped.
please i need help please post or email me at

Thanks Michael
