My car idles really high, 1600-1800 rpm. I sprayed carb cleaner around all my vacuum lines an gaskets to try to find a leak and cane up empty handed. If I unplug the MAP sensor while the engine is running, the idle drops to 1000-1100. The IAC valve was tested and turned out to be good. Is the MAP sensor bad or what else am I supposed to check.
