Has the check engine llight come on? Have you checked the catylatic converter to make sure it isn't plugged?

Before replacing any other parts, you need to have the computer scanned for trouble codes. Chances are there is a problem that is stored in the computer's memory which will identify the problem. If I had to guess at this point, I don't think the O2 sensors are the problem. I think you have a major vacum leak at the intake, but I need to know if any codes are stored in the computer. Or, if you have a vacuum gauge and can check intake vacuum for me, that would be helpful.
