1994 Jimmy 4X4
4.3 L V6


When i start my rig, it idles at around 3000RPM.  I've been trying to figure out what the problem is but I don't understand what the problem could be.

Someone told me that its possible some sensor was stolen?  What would this senson be called?

It was working fine yesterday but today I start it and it revs very high....

Could be your MAP Manifold pressure sensor is bad.
