HELP! Flooding Out! I had the car running good and one day I went to start it and it would not. I started smelling fuel and it was just dumping. I thought since it had sat for a while, maybe it was a stuck injector. I unplug one at a time and when I got to #7 it fired right up and ran. I pluged it in and flooded! So I replace injectors and its still doing the same thing! HELP?

I'm a little confused but... if your car is "flooding out" it's and you've replaced the injectors you've either got a real bad exhaust leak, your leting unmetered air in the intake, or your plugs are just bad. how are your plugs?

Brand new plugs! And I think it might be my pcm. I reprogramed it just for giggles and it fired right up! I ran it for an hour then drove 30 miles and its running perfect! Anyone ever have an issue with the PCM like that?

Humm... when you reflash the computer the fuel trims are erased and new ones have to be made. Maybe your o2 is messed up on that bank. And when you start it up after flashing the computer inputs the fueling as required by the mass air until closed loop is in effect and short trims are now being made. Now after a few days the short trims are constantly showing the same fueling changes to get it to be placed in the long terms. And BAM! now when starting if in open loop or closed loop it will use the long term trims which are too rich.
or it could be something else like an injector messed up. lol
