MAP sensor code came up p0108 replaced MAP sensor worked okay for a day or two and doing the same thing again. I'm going to do a vacuum check tomorrow. Anything else you could think of that would be a good idea to check or know of any common problems like this and quick fixes. Please let me know if you have any questions or concerns or ideas, please. Thank you, David Spray

This is common when the catalytic converter needs to be replaced because the material inside breaks down and melts together effectively clogging the exhaust system. This guide can help confirm the problem and I have included how to change out the converter in the images below:

This guide can help walk you through the steps it is one a similar car, but the procedure is the same:
