High fuel pressure, stuck press reg in the TB, bad coolant temp sensor most common issues, weak vacuum signal to map sensor also.

What is a "violent temp"?

Put a scan tool on that vehicle. Read the data stream. Tell us what the coolant temperature is, what the short- and long-term fuel trim is, and tell us how many O2 cross-counts it has.

My guess is fuel regulator.
