Hi i have a 1990 excel. I picked up this car and it was running bad, the owner didnt know what was wrong with it so i tried to fix it. I replaced the fuel filter fuel lines everything to do with fuel and it wasnt it i need some help fixing this. I can drive it fine for like 5 minutes or so then it starts bogging down like it is running out of fuel, it eventually bogs down until it shuts off. I am thinking maby an 02 sensor but im not sure. has any one else had this problem, any one have ideas to test if its the 02 sensor.

Thanks for looking and please if you can help do.
