I have a problem with my truck running rich. I can smell it in the exhaust pretty bad. It has a slight miss while at idle and only idles at about 650 rpm. I have replaced both o2 sensors 3 times. A new map sensor, Idle air control valve, throttle position sensor, plugs wires, alternator, distrib. Cap and rotor, new O rings on the fuels injecectors, new K&N air filter. I don't know what else to try. Nothing seems to work.

Here is the location for the MAP sensor in case you want to swap it out. Check out the images (Below). Please let us know what happens.

Hmm, that's not good! I would check the o2 sensors make sure they are working properly, also clean the MAP sensor. See if that helps.
