do you have a DMM, like a volt meter.
check the volatage going to it, should be about 5 volts,
and then check to see if it has proper ground.
then check the signal and see how much voltage it is producing at idle, shouldnt be much more then .5 volt to 1.2v
btw backprobe it with a t pin or paper clip even. just dont mess it up when you put it in there.
backprobing is putting a small pin in the back of the connecter and then put the red lead on that and a black lead to a known good ground, then bring it thru the rpm range, shouldnt exceed 4.5 to 5 volts, 5 volts is usually way to high thu.
is there a vacuum leak in your car?
posiblly take some propane, and spray it around vacuum lines and gaskets, if your rpms go up, theres your leak, and do it in moderation not to much.
if you f something up I take no responsibility
I dont know to much about these cars in general but if theres a hissing sound thru the vents, maybe the controls are vacuum operated and maybe one came lose and now you have a vacuum leak throwing your MAP readings off.
