Engine code 25 is on changed it twice sensor and it wants to turn off when i come to a stop and it floods out and turns off its 89 s10 2.5 liter

didnt specify year model or engine --generic answer --if the tbi is flooding ---check the fuel pressure regulator --and the tbi itself

Have you checked for a broken valve spring. Repaired a dodge engine with the same running issue as you have described and it was a broken intake valve spring.

Most likely is the temperature sending unit/sensor. Nobody ever thinks about how it works. When engine is started, and cold, the temp sensor tells the computer to put the engine into cold start mode, putting more fuel into the engine and to a bit higher idle. Once it warms up to operating temp, said sensor tells the computer to turn off cold start mode and it stops dumping excess fuel in. If the sensor puts it in cold start mode, malfunctions and doesn't take it off cold start mode, it's still dumping excess fuel in and flooding the engine. Sometimes a re-start will reset the computer, but not always. Makes sense now, doesn't it. Find the temp sensor and replace it like you did all the others.

replace fuel filter replace air filter,clean fuel injectors because they could be dirty clogged with carbon causing injectors to stick open and keep spraying fuel when engine off flooding engine.code scan for faulty engine coolant temperature sensor or CMP sensor.

What faults codes are showing on a test of the electronic engine control module?

flooding out is a furl /injector problem could be excessive pressure or leaking injector seal or bad injectors

do you mean the code reader is flooding meaning giving this code tons of times or are you saying the car is flooding out and you also are getting a fuel knock sensor code. The more complete thourough the questions are the better diagnosis can be given. The situation is the knock sensor is just that. it picked up some kind of vibration and in turns tries to protect the engine from any further damage. this is why the car is not starting. Usually this trips the fuel shut off switch and stops the fuel pump from running. Untill you reset the fuel shut off this will not start. Owners manual will explain location and procedure of switch.

try the crankshaft sensor. it is on the transmission bell housing on the passenger side. You could also check for codes by turning the key to the on then off 3 times (DO NOT START THE ENGINE) and it will give you any stored codes in the mileage display

You need a timing belt
