Car keeps flooding - 2005 Mazda RX-8

If it keeps flooding the carbs need attention. Time to take them off and get them tuned up.

Is car flooding? Leaking injectors. Is car not flooding? Bad fuel pressure regulator, bad fuel pump pressure, leak in system.

Unlikely it's flooded, but I did have a similar problem with my car, and replacing the temperature sensor fixed it.

Michael,
Flooding is a known problem with the RX-8 (unfortunately). It is designed to run at high RPMs for extended periods. Flooding typically happens if and when you initially start the car and turn it off before it has had a chance to warm up sufficiently. If it does flood, you can put a jumper cable on the battery (because this process will quickly drop your battery charge) and press the accelerator all the way to the floor (you should also remove the 20 amp fuse for the fuel pump). Turn the ignition for about 20-30 secs and then rest for 30 secs. Keep doing this (with accelerator fully depressed) until the car starts. It may take as many as 10 to 15 repetitions of this before it starts. If this does not work, then you will have to remove the left front wheel to access and remove the spark plugs (and repeat with the plugs removed).

think you put a dodgy part on no doubt a cheapy made in china part ,try a genuine bosch

Does it continue to flood the cylinder it it is unplugged from the harness ? ?
Could be a computer problem or a short in the wiring.

Define flooding.

1. Black smoke out of the tail pipe?
   

If the fuel return line is plugged,it will flood.If the fuel pressure regulator has lost its vacuum signal ,it will flood.

If there is a large vacuum leak,the O2 will see a lean condition and cause the rich condition.gas mileage will suck,big time.

This "flooding" happens when the engine is cold? ONLY?
Be sure the air filter is not clogged and the PCV is not plugged up solid.
Also,there are a few tubes from the valve cover that vents oil vapors into the air filter housing.

During this flood mode,hold the pedal to the floor and shut the engine OFF-it should NOT keep running.(Leaky injectors)...

Do this when engine is hot and cold.

I assume that your Buick has a carburetter. Flooding is normally as a result of a stuck or leaking float needle and seat. Replace these, also check that the float is not punctured and has therefore lost some of its buoyancy.

CLEAN FUEL INJECTORS.THEY ARE FLOODING THE ENGINE.WHEN YOU TURN OFF ENGINE DIRTY CLOGGED FUEL INJECTORS WILL KEEP LEAKING FUEL FLOODING ENGINE.ALSO REPLACE AIR FILTER.

Where is the gas leaking from? To clear a flooded engine, keep your foot all the way down on the gas pedal while you try to start the car. As it starts keep holding until it sounds like it's smothing out then slowly release. You can also change the spark plugs if that does not work.
