MAP sensor question........

[twizted91gt]

Is there supposed to be a vacuum line going to the map sensor on the firewall?....there appears to be a small "nipple" of some sort on it with nothing plugged in....reason im asking is im having some crazy idle problems as of lately(damn 10 degree weather) and its driving my nuts so i thought this could be a possible solution.............thanks

you could have a vacuum leak, or your tps could be dirty, check your MAS plug, make sure thats all plugged in.. If you have emisisons, check all the sensor lines make sure there all plugged in.. if not, you should try starting it when its warmer outside.. if not, go have the codes tested.. good luck !!

There's not supposed to be a vacume line to the map sensor.
