Why do I have to replace plugs after flooding the car?

Many people say you have to replace the plugs after you flood it because you fouled the plugs with fuel.

What I don't understand is.. if you manage to deflood the car and start it up without touching the plugs, will the natural combustion cycle not burn up whatever fuel that you have coated the plugs with?

Then, after some hard driving, wouldn't it for sure burn up whatever fuel you had sprayed onto the plugs?

I don't understand why the plugs need to be changed? They're not fouled anymore.


Can someone educate on this?

Blah ... I've never subscribed to that idea either footman.
I too would like to hear the so called "rational" behind this.

I have fouled my plugs bad enough to have to pull the fuel pump fuses, and crank and crank for like 30 minutes and then put back in and it started up. So to be this is an urban legend.

I think replacing plugs is more related to how long the car sat, before being started again...

what you don't understand is that there are a lot of uninformed people who think they are knowledgable

SO there really is no need to change the plugs if you manage to start the car with the same plugs afterwards?
