2000 Ford Explorer 2000 Ford Explorer idle problems

It could be other vacuum leaks like the intake. Has the check engine light come back on? If so, does it have a different code?

Let me know.

Yes the check engine light is on, took truck to autozone and they said the code means I need an 0-e muffler. I think this is incorrect. I let the truck run for a few minutes and there was a puddle under the exhaust and water coming out of the exhaust. I also checked the oil and the level is really high and there isnt much coolant in the radiator. I now think it may be either a blow head gasket or intake gasket. What do you think?? Its just funny that the first code said I needed an idle air control valve and now that thats changed all of these other problems are happening.

Does the oil look contaminated with coolant? As far as the code from A.Z., OE muffler, that is interesting. In the future, ask them what the code is and I'll look it up. THere is nothing that sets a muffler code.

As far as the engine, my first guess is the intake because of what is happening, but let me know about the oil.

The oil is a real dark brown, looks almost like melted chocolate, but it doesnt smell like antifreeze. Ill take it back to autozone to get the code.
Thanks,

Also, the truck has plenty of power. It actually runs a lot better since the tune up. But, the major problem is that the idle is WAY too high, and I think coolant is getting into the intake, or maybe its the head gasket, just dont know?
Thanks,
