I have an 03 Cadillac Deville Base sedan. 275 horsepower 4.6 liter v8. I have 122000 miles and use semi synthetic oil. Has no engine light and just recently replaced CAT because it was clogged and bought a new direct fit Walker one. Pretty nice one. So I just got it installed and wanted to floor it to see if it fixed the clogged cat problem before and it obviously did. I just wanted to know if it's bad to floor a car like this everyone's in a while. I have a pretty decent sized engine so I figure it wouldn't be a problem.
have the same problem?
