But . . . my car runs much better. My car is still sluggish when I accelerate from a total stop or go in reverse. But, it does it far less. Rather than threatening to cut off at every stop light when the air is running, not it only does it a few once and a while.
I changed the air filter on my car. That didn't seem to help the situation. But, hey . . . I can't recall the last time that car had the air filter changed. I don't think I've ever changed it since I've owned it.
I'll try some of that gas treatment stuff to see if that helps. After that, I'll probably need to take it to a professional car mechanic.
