96 Accord Power Steering Blet

My 1997 Nissan Sentra has 233,000 miles and the last time I got gas in it I noticed the acceleration was very sluggish, I tried fuel injector cleaner and gas treatment and neither helped. What else could it be. Thanks for any help.

I have a 1997 ford thunderbird 4.6 liter that blower does not come on. I was driving down the road and smoke came out of the vent above the radio and the motor stopped. I checked all fuses high and low and are all good. I checked the motor and it's not getting power. I replaced the controllor with same and it comes on but still not blower. The controller is a digital climate control and lights up and when i switch to either heat or a/c i can hear the vents opening but no blower. I put on defrost and it comes on but the blower still doesn't work. I was told maybe the resistor bank went bad???
