Will it hurt anything to loosen cat converter at header?
I just bought a 2000 Ranger 4x4 with 4.0, auto tran. 157k on it. I bought it knowing it had issues. I drove it home 15 miles and it has no power and will not climb hills very well. Also missing pretty bad, not as bad when idling. After reading up on the many possible causes, a bad cat may be the culprit. ?
So if I loosen the connection at where the cat meets the header and take it for a short test drive, will I risk damage to the engine? And do you think this is a good way to test? Will I have to put a new gasket in when closing it up?
