I wish I had a machine that would tell me what part was bad! :)
What data did your friend use to determine that those parts were bad? The 2.4 doesn't run right without the cat on, and the 2.3 is almost the same engine, so removing it isn't a good test to see if it was plugged. What was the exhaust back pressure before you cut the cat off? Any codes? Not all codes turn on the check engine light. Did the problem start all at once or get worse over time? What's the fuel pressure?
