Once and a while while driving my Duster 2.5 automatic I will be giving it gas and it just seems to bog down. It stays running just seems to have no power. I checked the codes and all I pull is the O2 sensor. I doubt the O2 sensor is making it run this bad. Any suggestions of what else to check?

If you have 100,000 miles on the car it is time to change the O2 sensor anyway. Yes the O2 sensor will do that.

could that be the same reason i dont seem to have much power when i accel at any speed
it just seems like i dont accel very fast or nething, even when i have it floored it doesnt seem like it accels that fast
could it be that or could it be becuz of the 3spd auto trans in it??

squeaky3 pull your trouble codes and see what the computer does not like first.

ok i
autozone will read the codes wont they?
i dont have a reader that will read from a 94
i work for ford so i have access to a scan tool but they r for ford and the like

i did have the check engine light flash on once in the spring but it only happened once so i didnt really worry about it to much

thanks

On a 94 duster you can pull your own trouble codes. Trun the ignition switch to on 3 times and leave it on the last time. Count the flashes.
