I thank you for responding.
The red hot pipe is after (downstream) from the Cat not before.
Here is what my research has led me to so far:
I believe the cat is working.
THe code I got "p0174" tells me the downstream(after the cat) O2 sensor is putting out little to no voltage. (lean=Low)
Which makes the computer run the engine rich thus giving the cat an extra work out forcing it to run hot.
A rich running engine is not efficient thus giving me the decreased responsiveness and power loss.
This is my theory. So far its only a theory.
I will try switching around the two o2 sensors to see what happens.
If the trouble code changes I will know I have a bad o2 sensor. If it does not then either the wiring is faulty or the Cat is gone.
I am still looking for help on this one so if you think I am on the right path let me know if not show me the light please.
Thanks again
