I have a 2003 Saturn L200 4 cyl. With 221,000 city miles that i've owned since it had 20,000 miles on it. It has alll of a sudden has a hard time maintaining 70 miles p.H. On highway, and exhast noise is load right under our feet. I have tuned it up, replaced the fuel filter, changed the air filter, and I was wonder ing if I should get the catalytic conv. Checked.
