i have been having a problem with my cylinders filling up with gas when the car is shut off, which makes it hard to start after sitting awhile. already put new plugs fuel pressure regulator and nothing worked does anybody have any other ideas?

 

Could it be one of the fuel injectors leaking after the engine is shut off? Just a guess.

 

i just replaced a four injectors and i still have the same problem its starting to be a pain in the butt

 

usual culprits are ignition and fuel regulator. if either of those are misbehaving in certain ways, the car can flood.

 

i already replaced the fuel pressure regulator and no change the other thing you are talking about is that the iginition coils?

 

the ignition system in general. a plug, a wire, or a coil.

 

Can anyone tell me where and how to replace the cabin air filter on my 2001 mazda Protege ES 2.0 ????
