It sounds like I have a vacuum leak, I can hear something thats like a sucking sound around #1 intake runner on the intake manifold I can spray carberator cleaner around it the rpm's go up.I have already replaced the iac and tps sensors, but at the map sensor I am reading under 5 volts on one electric connection and on the other one, nothing, and It should be reading the same.I was wondering if it could be another sensor and if I have to remove the intake manifold how hard it would be.

The intake manifold is a sinch, make sure you check all vacuum hoses though, they can be deceiving. You could have more than one leak, is your engine light on?
