When i unplug my idle ac sensor plug it idles better than with it plugged in. Some times ill get a cel with it unolugged sometimes not.
Acc. Is a little bogged down. What does this mean? Iac is bad? Plug is bad?

When it is plugged in car will stall on netural 1000 to 0 rpms

make sure you check other vacuum lines. you can try to find a resistance spec... other then that clean it out with maf cleaner, get the carbon out!
