You could try cleaning the pre-cato2's with electrical contact cleaner orjust anon-residue cleaner...carbon builds up and can effect their performance. And like Hardin said...cleaning the TB wouldn't hurt at all.

For the o2's - https://dodgeforum.com/m_1102906/tm.htm

For the TB - https://dodgeforum.com/m_1050644/tm.htm

EDIT: Added links

It only takes one tank of gasoline with higher sulfur
to "poison" the oxygen sensor's ceria solid electrolyte

On Chrysler vehicles one tank of gasoline with higher sulfur
can also cause the fuel tank level sensor to permanently malfunction
by corroding the metal resistor strip
