Aug 10, 2005 (2:18 pm)
interesting stuff, i'll add my 2 cents
Got a 2005 cyclone gray 6 speed in April with 80 miles on it, had the car over 100mph on the test drive, pretty much followed the break in to a tee (Minus the test drive of course). It has been my daily driver and I have over 7,500 miles on it and had no problems, until...
I've had the oil changed twice but the oil life meter never got reset properly and it went off a couple of hundred miles ago. I tried to follow the instructions in the manual to reset the oil meter: with engine off, turn key to ON, slowly push the throttle to the floor twice within five seconds, turn key to lock and you are reset. How hard is that? plenty, I tried many times but could not reset the meter....
this was literally 4 days after my last oil change and saw the mechanic follow the instructions in the book to reset the meter, unfortunately there is no indication that it has been reset other than it is not on any more but if it's not on to begin with...
Anyway, I was out of town and was trying to wait until I got to my local dealer but kept trying to reset the meter. Apparently, I confused the computer into "safety mode, reduced performance." Unfortunately, I was on my way back to a meeting so couldn't do anything about until later, and let me tell you, you do NOT want your car to go into "reduced performance" mode, it should be called "no performance" mode
After my meeting, I was on my way to the closest Pontiac dealer to fix my car. When I re started it, it was no longer in "safety mode" (thank God) but the "check engine" light was on and the oil life meter still hadn't been reset
The service manager at the dealership heard my story and explained to me as we walked to my GTO that in every other GM car, you have to press the gas pedal 3 times in 10 seconds. He didn't even do it slowly, and boop, reset. I showed him the manual and he said he was going to notify GM about the misprint, whatever....my car was reset
The "check engine" light was still on and I was told that the computer will "hang on" to the fault code for approx. 10 engine cycles (warm up- cool down) even if the condition that caused the fault is no longer there. The next morning, the check engine light did not come on and it has been fine ever since.
So human error can be blamed for that problem although confirmation of a successful reset would be wonderful.
As far as the throttle response being sluggish? You bet I've noticed! My car seems to be inconsistent from the line. There has been a time or two when I've taken off and haven't hardly been able to keep my head off the head rest while other times it's like "come on baby, you can go" When the car is cold, it feels most sluggish. It seems the computer program needs some tweaking.
It's all starting to make sense. One thing I have noticed and even told my friends about is that turning off traction control is like unleashing the beast. It felt as though a brake had been released. My assumption now is that the computer reads the acceleration table differently as it behaves as sputterguy described in his test drive, "would chirp the tires when I tapped the throttle."
gas mileage for me has been 14.1mpg at the lowest and 25.5mpg at the highest. A 1500 mile trip that took me through the mountains of WV had an average of 21.9mpg (and believe me, I at least maintained the 70mph speed limit, even up the steepest 5-7% grades)

Aug 10, 2005 (4:03 pm)
thanks for the SPAC idea, Robert. i mentioned it to the dealer service manager today as he checked the broken seatbelt adjuster. he was noncommittal on whether he would make any of my parts 'spac orders' but he did say the parts would arrive while the car was in body shop next week. so maybe that will work out nicely. one of the newer service reps said no way would they do a spac order for these kind of parts - he made it sound like that was done only when a vehicle was undrivable, or something major was needed. whatever, i'll see how it goes.

I am glad they did not produce as many GTO'S as the over produced new Mustang. Who wants to see the car they have in everyone's driveway.
By the way gxpgtodanman, how do you like your GXP my wife loves hers. Turn off the traction control and that car will smoke the tires almost as much as my GTO.

i have an 05 6 speed and the best mpg i have hit is 25.5 going 55-60 mph. I do not think you would get over 15 mpg at 90-100 mph. The wind resistance and higher rpm's would limit you.
Aug 10, 2005 (7:47 pm)
I have a hard time staying off the throttle in my 05 6 speed at age 37 and I have had some fast cars in my day. At age 16 I would have had 10 tickets for wreckless op in the first week if i had not yet wrecked it.

???} is silver.I ordered the full SAP but was told by my dealer that there were three seperate order numbers for different package's. Since I have midnight blue mine came primered and it cost me $600 to have paint matched, for a total of $3700 for the SAP.

The engine must be warmed up; doesn't do it cold. A/C makes it worse, but it is there without it. And it only does it in D. If I let it roll while in D and just idling it goes away shortly after moving. BTW, I failed to mention that the dealer checked idle speed and said it was to spec.

Me too, and 66% of those Mustangs are the base V6 and rental ones anyway. Hertz by me always has 3 or 4 at any given time.
It's kind of funny burning the front tires. You better have the windows up otherwise the smoke will come in. I have already stunned quite a few Mustang driver with GXP. I beat one 2 lights in a row and the guy asked what I had done. Nothing, stock from the factory. Don't forget, GXP insurance is lower then Mustang too.

That's because the idle speed comes up as speed goes up, even without pressing the gas. It's supposed to do that. Your problem could probably be "fixed" by raising the idle speed a hair, but that sounds more like a bandaid fix. You have the exact same PCM calibration as others who have no problem, so that's the wrong place to look. How many miles does the car have? Under 5000? If so, give it another oil change, like I said before.

I noticed on the GTO's oil filler cap that it says Mobil 1.
I assume that is the prescribed oil to be used in this car and also assume
that it came with this oil. I know that Mobil 1 is more costly than regular oil
and my question is: How often and at what milage should one change the oil under normal driving conditions?
I have been told that this type oil is superior and used in most high performance cars such as the Corvette and is the choice of NASCAR.
