Default 2002 Honda Civic ex engine light on and code PO128 on acanner

For the last couple weeks engine light keeps coming on and maintenance required light has been stuck on for a month. The oil is fine and so is coolant. But my car for months has been smelling like gas and this morning when I got to work I turned it off to open the gate at work and I tried to start it it and it would sputter and then die when I was giving it gas. I tried a coke more times and I finally got it into the parking lot. I thought maybe it needed coolant but no it’s full and it’s not overheating. HELP I am at a standstill anybody else come across this problem. Oh and btw it’s been a few hours and it started right up. Uugh

Put a new Honda thermostat in it along with Honda coolant, clean throttle body, and put a new set of Denso spark plugs in it, clear the codes and run it.

p0128 is probably bad coolant temp sensor, buy a new one and install it
