I tried the ECU reset, will see what happens....btw, I was on another site reading some service bulletins. You can only print up two a day as a free member and I just printed the second one up when I saw this one...not sure what it says or means as I can't open it up. Its probably not a biggy, however:

ITB02-055
2003 INFINITI G35 COUPE; BATTERY SERVICE PRECAUTIONS

If the battery of a G35 Coupe is disconnected while:
• the doors are closed and
• the windows are in the fully raised position

 

what happens if its disconected while the doors/windows are closed....

 

This is not true. Fuel economy has no direct relation to engine RPM's, and everything to do with how far down you are pushing the gas pedal. You could be driving your car with the gas pedal pushed down 1/2 way in 6th gear at 1600 RPM's, and be getting 7 MPG during the duration of doing that..... or you could go at the same speed but in 4th gear with your foot lightly on the gas and at 2900 RPM's, and you would be getting something like 18-20 MPG during that duration.

Fuel economy is basically broken down to speed divided by throttle position. It doesn't matter what gear you're in or how many RPM's it takes for you to be at that speed. The optimum fuel economy is usually achieved by finding the right gear to be in so that you can cruise with the lowest Throttle Position % possible.

 

I couldn't open up that TSB as I had already downloaded two others for the day....I was hoping someone else knew?

 

Sorry Tofu, I don't care if you're driving thru hills or desert better mileage
can be achieved by using the cruse control. If I can take my wife's Vet
and drive from here to NoCal and get 24 MPG that's just remarkable. Plus
with the cruse on I pass all those tards that can't maintain a constant
speed. I see this daily, drivers going uphill speed drops to 40 MPH and on
the downhill it's more like 70+ MPH. Great for mileage....

put a big brick under your gas pedal and all yo problems be solved.

 

Just wondering why you do this? Isn't 35 psi 35 psi, not matter how big the tyre is?

 

You are 100% correct Blue Meanie...PSI stands for PRESSURE per SQUARE INCH...IT DOESNT MATTER HOW BIG OR SMALLER A TIRE IS TO THE ORIGINAL, THE PRESSURE WILL STILL BE THE SAME AT 35 PSI. Think about it most all cars have relatively a 35 PSI regardless if the car is a sedan or an SUV. Check it out and you'll see what we mean.

 

I realise that, hence my question as to why a bigger tyre needs more psi

 

I filled up last week and drove 438 miles and still had gas left.

I come from driving a Tundra...I think this G gives PHENOMENAL gas mileage.

 

how.......I have an 04 and I get roughly 220-260 on a tank...I have alot of mods on my car but most are air mods...I have an automatic as well with a VB upgrade but typically drive in manumatic mode.

 

99% of my driving is all highway...I keep it at 55-60mph and shift below 2500RPMs ALWAYS. I use Mobil 91. Mobile 1 oil. Keep the tires at the right PSI.

I have yet to push the gas pedal and see what the car can do. I haven't gone over 3K rpms honestly.

 

no wonder you get 480 you granny drive the car lol like g35 man said were lucky if we get 220 on a tank... this is rediculous i only got 103 miles to a half tank again this is HORRIBLE man... gotta be something wrong with mine

 

I dont need to go fast or drive hard.

I take my time and drive patiently to get where I need to go.
