So I get home last night and park, of course the engine is loping as bad as ever. I pop the hood and pull the plug to the MAP sensor, and ..... WTH!!!!!!! The idle smooths right out and stops loping. I snap the plug back in, and it immediately starts loping again. I do this ~3 times and it does the same thing each time.

Is this a conclusive test that at least my idle problem is due to the MAP sensor even though it doesn't throw any codes? I will bust out the multimeter to test it if I can find the test procedure, but if this is conclusive, I won't waste my time. Or is my "out of range" TPS fooling my MAP?
