Default Camaro Flooded after driving for 10 mins

My camaro has a problem with starting up after it has been running for like 15 mins or more. It still has the stock fuel system. The whole car is bone stock. It has a problem starting up after it has been running. If i keep my foot on the pedal to shut off the injectors and let the fuel in the cylinders burn the car will start up but miss real bad for 15 seconds until it burns the fuel and then runs normal. Im just wondering y it is getting flooded? What would be causing this.?

Possibly injector stuck open. Allowing fuel rail to drain into cylinders.

Ya but it will only do that after i been driving it. If i leave it over night it will start right up. I mean the car has extended crank when turning over. It takes like 5 seconds to start but it will always start if left over night. But if i drive it and cut it off it has this flooded problem.

dumb question but have you recently worked on the exhaust?

I accidently crossed the 02 sensors, left in right and vise versa. My car would run fine for about 10mins then it would flood out. As soon as I switched them it was fine again.

Replace the coolant temp sensor. It's not telling the pcm that the motor is hot so the pcm is still fueling like it's extremely cold.

ive replaced the temp sensor. its still not working. it still showing -38 on the snap on scan tool and the when i jump the wire it reads 238 like it suspose to. i dont get it. the sensor is new but the car is still not reading the sensor. Also the car does not hold fuel pressure when it cuts off either so it might be both problems. But i dont get y the temp sensor aint working.

Sounds like you have a broke wire in the harness somewhere and possibly a problem with your injectors also. Fix the wire problem and then drive it a little to see if that stops the problem.

the wire in the harness is not broke beacuse when i jump the wire the temp. jumps from -38 to 238. All data says that is correct so there is no broken wire in the harness.

Correct. By jumping the connection you would either read full cold or full hot. (I cant remember.) In turn that rules out wires. If there were an open it would either read full hot or cold. (again because I don't remember.)

Ohm out the coolant temp sensor.

EDIT: Also how did you jumper it? Make sure you didn't spread the terminals. It the don't have good terminal tension it will seem like the sensor is unplugged when in actuality it is.

the terminals are good. even when i wiggle the it while the cars is running it doesnt do anything. i figured mayb it wasnt getting a good connection but it is.
