Could be a clogged catalytic converter.

I agree with Dorian on that one. Stop in at a muffler shop and have them check it out. If your state allows it you can simply have it removed. It's not worth replacing it on an older car. Unfortunately, with the myriad of sensors and sensitive electronics on modern cars there are probably several other things it could be. You need a properly equipped mechanic to trouble shoot it for you so you don't spend hundreds or even thousands on unneeded parts.

thanks so much for your help guys and for sure will actually have someone check out the Catalytic converter

before you remove any catalytic converter,,have your map sensor checked first,it could be a false reading showing converter,however the bog may be coming from a faulty mix of air and fuel to the converter,,
