So last night when I went to start my van, I flooded it. I was being very stupid with the gas pedal and floored it a few times to try to vent out the fuel, but that made matters worse.

At full throttle it was stumbling and couldn’t stay running.

How long should I wait to try again? I’m picturing the spark plugs dripping with fuel and hoping I don’t need to replace them!

It's normally oil that will follow the plugs. Wait 30min or pull the fuel pump fuse and crank for a bit with the pedal to the floor. Do you have a leaky injector?

Tonight I tried to start it and it had the same symptoms. I could get it running and keep it running with the pedal almost to the floor, but it was definitely misfiring.

I’m thinking the plugs are just fouled from all the gas. The gas smell was very strong.

Any advice on changing these plugs? I’ve read a few are difficult to access — is there a specific extension I should use to get those?

Honestly I don’t think these plugs have been changed in twenty years.

Assuming it's been awhile, do a full tune and report back - plugs, wires, cap, rotor, air/fuel filter. As mentioned above, oil fouls plugs, not gas.
