Ok. it'* actually about 25 degrees outside, BUT that'* beside the point. In my dash, my external temperature reads as being 125 degrees right now. It started about a month and a half ago. It was probably about 30 out, but the temp read that it was about 41. I figured it was just a warm spot or something of the sort. Problem is, it started climbing everytime I started the car. Now it reads well over 100 and it'* still climbing. I did some searching on here and found the answer to my other problem (Both rear windows dropped within a month of each other, so doing that fix you guys wrote up in about 2 weeks when I get time to). But this problem has me stumped, and I didn't see anything in my searches as a problem that'* been had before. Any ideas on how to fix this or what is causing it? It'* not a necesity, BUT when driving and it'* drizzling or raining, I like to know the general temperature so that I know what kind of icy/just wet conditions that I'll be dealing with. Any help would be appreciated.

Maybe someone can help me with a search on this. Not even sure where to begin to search.

On startup, the car occasionally sputtered. This went on for about a month, then it would occasionally sputter and completely stall out UNLESS the instant it started I pushed the gas pedal down. It was time for general maitenance anyway (75k miles), so I changed out the fuel filter. Problem disappeared. Now it'* doing it again, and it'* been only 3 months since I changed the fuel filter, oil, and plugs. Any idea? All hoses seem to be in place just fine. Either link what you have so you don't have to type it all out, or tell me what to search for so I can find it. Thanks.

well not quite sure how the temperature is read in the cars but I know if you stick a long thermometer into a tight container then break the glass inside the container the mercury will actually climb the thermometer as if the container was getting hotter. (happened in a science experiment in grade

Could be a few things. The shop manual highlights the problem could be caused by a bad engine coolant sensor, a bad vehicle speed sensor or a bad ambient air temperature sensor.

If you haven't noticed an unusually hot engine temp on your cluster, I'd be most inclined to start with the ambient air temperature sensor behind the front grille. You can start by checking for any obstructions around the sensor. Also, if you have an ohm meter, you can try the following:

1. When you have the inaccurate temp displayed, measure the outside air temp with a regular thermometer (close to the front grille area).
2. Disconnect the sensor behind the grille temporarily and measure the resistance across the sensor terminals.
3. Double check there is no wiring damage to the sensor connector.

Post these two values to this thread and I'll see if they are within spec. You may just have a defective thermistor.

I would look into replacing the ambient temp sensor personally. Last I heard they were very cheap. (don quote me on that though)

as for the sputtering and such, consider plugs and wires as a large possibility

I just changed the plugs (Bosch Platinums), so I'll do the wires in 2 weeks when I get a chance. I'm having my friend at a GM dealership check on the ambient temp sensor to see how much it is. I'll post up the price as well as the numbers that Ddalder requested as soon as I can.

Not postive on this...but maybe the sensor is coming in contact with something hot? IIRC ont he H bodies, the ambient air temp sensor is located right in front of the radiator? Maybe you hit some snow or something that pushed it back so that its coming in contact with the fins of the radiator? Because I do think you said it is increasing with the temp of the car, and coolant temp would make perfect sense. Just see if there is anything close to it that is hot. Maybe someone with an 00+ could help yah on the location.

And offtopic, but get those bosch plugs OUT of that engine block! these engines don't play nice with bosch. use another brand like NGK, autolite or champion. No bosch.

get those bosch platinums out of there and get some Autolite or AC delco... bosch are known to not be compatible with our engines.. especially platinums in a supercharged application.

*edit* check petraman'* sig for proof! --> http://www.bonnevilleclub.com/forum/...=821349#821349

i would also replace the temp sensor, or at least take a look at it...

On the outside temperature problem...

My friend at a GM Dealership is getting me the Ambient Temp sensor. Price is $12. I'll start with that. I honestly don't know much about GM'*, so when it came time to buy my plugs, I just went with the little bit that I did know. I'll go grab some AC Delco and new wires and fix that problem up as well.
