HELP, I'm getting BAD Milage!!!
Guys, My car is about 1 year old now, has roughly 36,000 KM's on it.
And I've been noticing that my Maxima doesn't feel quite right, even before my last Oil Change 4,000 KM's ago.
And Now ... I'm Getting Very Bad Fuel Consumtion?!?! I haven't actually Used the ODOMETER to see exactly yet ... but the Fuel Guage drops a LOT Faster than before.
I first noticed that my Max, doesn't have as much "GO" and after the Oil change ... it got a BIT better, but its still Feels "BOGGED"
What do You guys think the Cause is??
I always check my Tire Pressure, so It CAN'T be that.

What does That mean?
And how much is this gonna cost me?? Cuz if I get my Dealership to check it out for me ... they will Charge me UNLESS they find a Problem which will be covered under Warrenty!!

Im not shure how much shops charge for this but they do sell the compression guage at auto stores. Its a guage that you put in place of a spark plug and then you crank the engine about 5 times and it will tell you how much psi.
cylinder leakage test kits require an air compressor. what that does is that you put the piston of the cylinder that you are testing in Top Dead Center(piston all the way up) and connect the guage and it will see how much air leaks past the rings.
agin I dont think you will need to do these test. just get a tune up

Being that your car is so new, I kind of doubt that it could be things people mentioned which are normally the culprits on older cars or cars with more miles then you.
Also, the powerloss and fuel consumption increase coming about after the oil change is fishy. Where did you get your oil changed? I don't know if bad oil, leak or lack of it may play a role in fuel consumption but it can very well lead to a powerloss, thus causing you to push the car harder to get it up to speed you want to be at. pushing it harder = higher fuel consumption.
Malfunctions of these things can all cause bad gas milage:
-O2 sensors
-Fuel filter
-air filter
-spark plugs
-fuel pressure regulator
-leak
-sticking or clogged injectors
-tire pressure
-MAF sensor
-coolant temp sensor
-catalytic converter
There are more, most things relating to the fuel system or air/fuel mixture can cause it... also dragging brakes, tire pressure, etc..
Powerloss can result of most of these things as well.

So with this all said ... my best bet would be make a list of the "Symtoms" and bring it into the Dealer right?

Sounds like a O2 sensor might be going out or not reading properly. I would reset the ecu, if that doesn't work, its probably one of the o2s
