I changed the plugs and when I pulled one of the plugs a lot of moisture dripped

What is your question?

off the plug I smelled and smelled a little like gas also when I drove this car for a test drive from the start I would floor the gas and the engine kept running at a high RPM I hot to throw it in park and shut off the car. I pumped the pedal and it went back to low RPM but this car has done this several times is it a linkage problem
