Im sure if you all know how difficult it is to access the sparks plugs on a 00' 3.3l Sport Caravan.
I did not at first.

Long story short, I was trying to replace spark plugs. Could not figure out how to access spark plugs on the left side (if you are standing on the left side looking towards the belt.)
I could not remove the stupidly long intake, so I gave up and put everything back together as it was. Now when the van starts it idles at 3k RPM, and if I give it gas, its revs to 4k RPM and just sits there.

I can do basic repair. But nothing serious.

Ive checked vacuum hoses, sensors, fuses (just in case).
I replaced the hose with the PCV valve on it, and the valve itself.
The engine light is not on either.

Ive tightened down everything down.
Ive quadruple checked everything.

Please help, I need my vehicle running before the 14th. College starts.

 

"so I gave up and put everything back together as it was." What did you take apart?

Have you checked the Idle Air Control (IAC) valve and Throttle Position Sensor (TPS) connections on the top and back sides of the throttle body?
