1995 Buick Century Repair Question


Topics covered: Sensor, Spark, Gas.
Mileage: 170,000 miles.

Asked on February 26, 2012

My Buick has a problem, when I start to drive it, it runs great! When it starts to get hot, it bogs out and miss fires.

I don't know if it's spark plugs, I changed the fuel filter. I've put in injector cleaners to try to clean that up. I did notice that I have a pretty big dent in my gas tank closes to the motor. I don't know where the fuel pumps sits in it, but it does it when I have a full tank of gas as well. Could it be vacuum seals, or is fuel problems, or it something wrong with my motor? Could it be a trany problem? Or is it electrical? I am getting frustrated because no one can figure out what is wrong with it.
