I am still haveing alot of hesitation (lag) when I drive after replacing the oxyg sensor. It idles great but take off and no power. Any ideas?
 


are you getting an SES light? even if not, check your mass air flow sensor. i replaced the front O2 sensor and the MAF when i got the car, i don't know how it was even running. did you change both O2 sensors? if it idles smooth and it's just a dog when you're driving, you could have some flow problems. check your filters, oil, plugs and plug wires, little stuff like that. do you have a gt or a gtp? how many miles?also, i bought my mom a new car to get her grand prix from her, and there was a bird's nest in the air filter box lol. you never know what you can find.
