Where is the computer hook up at in my Cadillac sts Seville 01. I need to find out codes.

What is your question?

My car will crank up just fine then right after it shuts off. The car when it does run. It only goes 30 mph. It seems that the gas pedal only can be lightly tapped not pressed. In order for it to go. It won't pass emissions and the cat has been hollowed out. The O2 sensors are still in. The car has small vacuum lines. They broke just by touching them because there so brittle.

What makes this problem better or worse?

Better? Nothing. Worse. Does it get worse?

How long has your 2001 Cadillac Seville had this problem?

2weeks.
