Car just started running badly as if it’s not getting gas changed the cats n it’s still feels as if it is not getting gas if I push the gas peddle to the floor

(1994 Chevrolet Caprice)
My temp sensor never worked so I changed the coolant temp sensor n it still does not read. But checked w/infrared temp and one of the cats was almost 700* the other 260* so I had them changed with new ones changed the fuel filter and straight wired the fan to a toggle switch to make sure it’s on and it’s still running like poop what could it be
What seems to make the problem better or worse? Runs better once the car has accelerated ated
How long have you had this problem? A few days it came out of no where went from driving great I parked to running badly as if it was not getting gas and over heating

Coolant temperature sensor is what provides the control module fuel enrichment signal / data - that sensor and it’s circuits MUST BE functional !!

Good luck!

CTS circuits can be easily tested using a paper clip and proper scan tool.

CTS malfunction is one of the reasons the check engine light is on - not to mention running rough.
