Had my D at AutoZone again to put test on it after replaceing the plug an wires at the PCM box,, They told me Code P0123 Throttle sensor volt low,,,, Code P0107 manifold absolute pressure sensor volt low ,,, P1296 no voltage ,,, my motor is idleing from normal down low under 500rpm's then back up an then smooth out then starts doing the samething,, When I give it gas then it hesitates then go's an if I let it set there an run then it keeps going up an down then dies,, Seems to me like everything is pointing to my PCM box,, Like I said before that all this happen after I put my new power & heated mirrors on an ran my rear defrost that morning for about 20 mins,, I am sure my mirrors wouldn't have anything to do with this but just letting you know that this was the only thing I did to my D after putting new tires on it an the new mirrors,, Any idea's out there on this,, I did replace all 3 sensor's,, An the PCM was replaced about 5 month ago,, an tuneup,,

 

Did you check the circuits and verify you have low to no voltage? And if you had, what were the voltage reading.

 

No, I didn't check an not really sure how to check an been reading the manual to see how,,

Thanks Master Tech,, I will get to it tomorro an see what I find out,,

 

Did the test an found out the Map Sensor was bad,, I replaced it an now running great again,,
