I got the GXP out of storage on Friday and I was greeted with a few issues. First, the battery was dead. No recharging it possible. The storage company obviously did not start it once a month like they promised... so anyways $150 for a battery

There was also a faint buzzing noise coming from the dash area. I took it to the dealer and they said it was an aspirator? I don't know what that is but they said it is a temperature sensor of some kind. IDK, I had never heard of it. anyways, that is on order.

When I drove the car Friday night, I thought it felt weak but couldn't be sure since I hadn't driven it in a year. When I stored it I put it away with a full tank of premium and treated it with fuel stabilizer. It turns out that fuel stabilizer must just work enough to keep the car running... I filled it up this morning and dropped in octane booster and fuel injector cleaner and SHE IS BACK! She is breaking the tires loose and pulling hard like I remember. So, I guess the lesson is, Fuel stabilizer doesn't exactly preserve fuel.

Finally I got a new set of tires put on it. I bought four Potenza RE960 AS Pole Position tires. I went with all seasons since I am moving back to upstate new york soon. They feel good right now but I haven't "tested" them just yet. I will update in this thread. Price was great, for the factory sizes, all four came to $932 installed, before a $75 cash rebate.

I promised you guys some videos / pics and I haven't forgotten! I am moving into my new apartment today so I will get to some media this week.

 

ya i have a feeling after the winter storage my gas broke down a little too. I used the gas treatment also. After driving the car for a week its coming back around. I disconnected my battery when i stored it. Only stated the car twice during the 6 months.

 

A battery maintainer was the best 12$ I ever spent. I use it whenever I leave something sitting for more then a week. I always used stay-fuel over the winter and never had any issues. I use it with the lawnmower,sled,etc and never had any issues.

 

Welcome home man! ::

 

Congratulations on getting GXP out of the woodshed.

Sta-bil fuel preservative has worked well for me, gas a year or more old still fires up like...gasoline.

My experience these days is most folks don't even listen, much less do what they say they'll do.

I have that funny little noise somewhere in the dash after I turn it off, I figured it was some sort of magical device which will enentually break down and require 300 bucks to fix it.

 

Why did you put it up for the winter when you live in South Texas?

 

I think he was deployed.

Welcome home!

 

Yeah, welcome home. I am sure you are happy to be back.

Welcome Home sorry for my confusion.

 

Tell me about it. I won't fail you though Neanderthal.

I would have used a battery maintainer or disconnected it but the company that the army contracted to store our cars said they would handle it...

I also think the fuel stablilizer may have been fine for a winter (6 months) but for keeping it for 12 months straight, it just didn't do the job.

And thank you for the welcome back. I am excited to get the car back to the craft shop this week and do some serious cleaning. I will take pics and videos of my exhaust before I go to flowmasters. (Someone asked a couple months ago how the cherry bomb turbo IIs sounded on it, can't remember who or what thread...)

 

Did this resolve your issue? I just bought a used '08 GXP and it also has this buzzing sound coming from the dash. I was looking at this part for replacement based on your comments: AC DELCO AMBIENT TEMPERATURE SENSOR (AC1550101).

It is not the speaker(s) and it buzzes with the key in the run position (engine on/off does not matter). The buzzing will vary, sometimes it is nearly inaudible and other times it is much louder. It definitely seems tied to the electric system as the pitch will change slightly when I turn the foglights or bright lights on/off.

Does anybody know how dificult it is to replace this component?

 

I have an 08 GXP with the same buzzing sound. It just started happening.

 

It is easy to replace. One is under the knee bolster and there is supposedly one in the headliner. The headliner one is what the dealer replaced for me a couple years ago (according to the receipt). They just unplug. That did resolve my issue but the noise is back again. I guess cold weather really does a number on these sensors.

 

Thanks for the feedback! I'll try taking the knee bolster off to have a look.

 

It's right in line with the ignition. Drop the knee bolster carefully b/c you will have to slide the sensor out of it's "port," for lack of a better word.

 

I saw this thread and was thinking you got deployed again!

 

Thankfully, no. 2 1/2 years in Iraq was enough. I am enjoying civilian life now.

 

Glad your home for good

 

The part about it being right in line with the ignition...could be coupling noise. I have the same buzz and its kind of a wavering sound that changes with load. I wonder how it is grounded.
