since i had my tire popped and was running on spares for couple of days..and now i switched back to regular tire and i notice ALOT OF POWER LOSE....when i push hard the gears dont seem to catch up and catch down fast enough..my car has 14000 miles now and i felt like losing some power after 8000 miles.does anyone feel losing power after putting on some miles?,.,can it be the tires that could cause loss of power feeling and some alignment shaking....sorry for my bad english...

Have you had your car serviced lately? Clogged air filter, injectors..you know. Are you switching back and forth between regular and premium? You maky want to take it in for a check up.

Yep. My car does feel a little slower and less responsive. I mash the gas and it seems like the car has to think first before it downshifts to a lower gear. I mean, I'll be in 5th and when I floor it seems like it doesn't want to downshift and go the way it used to when I bought the car. This happened after I hit 7500 miles.

you guys are just used to it. drive any other car for a day and you'll feel better.

as long as you perform the maintenance mentioned above and oil changes. of course depending on how hard you drive, you may cause oil and tranny fluid to need changing earlier.

it will also drive different depending on whether it's warm or cold and if you always allow it to warm before pushing it.

I think the tire change is just a coincidence, you should take it into service under warrenty to see if anything is wrong

MaxMus

I don't think this is my imagination. I thought it was maybe some bad gas, so the next three tanks I refilled at 3 different stations. Same exact problem.

For example, if I am cruising on the highway at 60 mph, and want to floor it so I could overtake another slower car in my lane, as soon as I floor it, it takes up to two seconds to process whether it should shift to 3rd or 4th gear, and then it eventually shifts and the car begins to scoot.

This is odd because when I first bought the car, the slightest throttle press and it would want to shift down a gear. Now it seems like the car is trying to use more of its torque to move the car, instead of downshifting to a lower gear.

The oil was just changed and I don't drive it much since I've been off of work for 3 months, and I always let the engine warm up at speed on the highways before I floor it.

Maxmus: yOur car is fine .... I felt the same but I realised .. I got so much out of this car .. after a while I thought it was not doing much! but as nismo said

Proceedbob

Your car contains an adaptive ECM and will profile itself to your driving style, pull the battery cable (30 min) then drive it like you stole it for awhile, all will be good. My friends auto Max is driven mostly by his wife and it drives like crap, slow shifting, in gear to long........... Running on a donut could have tossed a curve ball to the ECM.

04BlackMaxx

Really? Thats pretty cool...I never knew about that.

i got used to the max's high hp, but after driving a camry for a day or two i really realized the difference and got the same feeling as the first day i bought my car. i guess u take things for granted after you have it for a while. but i am pretty sure Proceedbob is right about the ecm, it does it to get better mpg to by suiting ur driving style.

SilverBelle04

It could be because the weather is hotter now witrgh the arrival of spring .........i know that mine feels slower in warmer temperatures.

i agree maybe you are used to it. I was thinking of picking up a berk intake. maybe this will give you a little bump in HP.

James_05SE

I agree. You get used to the power after a while. My car prior to the Maxima was a 420 hp 1985 Camaro that ran 12.30's with nothing more than the addition of ET Streets. That was my daily driver. after a couple months it felt slow to me until I had a friend drive while I was in the passenger seat. Nothing feels slow when you are pushed back in your seat that deep at 110 MPH...

joffy

hey, if you really want to downshift faster switch over to the maunmatic mode and kick it down. then hold on, lol.

05MAXIJJ

yes when im on manumatic..it seems to really full but kinda feels like little harsh on my ride when the rpm climbs 5k ish...well maybe tire rotation is the problem or like nismo said maybe im use to it..so i decided to drive my old 2001 TL for a while...

yep, on auto at 80mph it in 5th gear... shift to manualmatic and down shift to 3rd gear and feel the power....

05MAXIJJ

JUST TRIED IT NOW..LOL
80 downshift to 3rd gave me around 4.5k RPM all the way thru redline car pulled crazy hard..but than again put it on auto and car shifting was kinda delayed.

then get the max checked out, maybe somethings up with it. good luck

Tek-Niq

remember the auto changes too early... you won't get that kind of pull in 5th gear..

NismoMax80

exactly. if the auto and manual modes were alike, it would be almost pointless. Auto's purpose is to keep the RPM as low as needed. If any issue, "The auto tranny seems slow" will incurr "We cannot repilcate." Other unlikely responses are, "Tranny flush for $xxx?" or, "then you should have gotten a 6speed."

along with becoming accustomed to the strength and speed of the VQ (making it seems slower once the newness wears), driving in Manual-mode, feeling those RPM soar will also make Auto seem sluggish.

05MAXIJJ

another question is when i put on manumatic and floor to almost redline and shift up and almost redline and shift up. would that cuase little damage or any to the engine?

Tek-Niq

iTrader: (3)

if you don't shift ever on manualmatic it will do it by itself, it shifts before redline so it don't damage itself.... try it..

04blackmax

that sounds rough on the engine. thank GOD for the 6 speed manual

It's all about the downshift with the manumatic

98BlkGle

HAHA very true

Tek-Niq

remember that while on drive it becomes a smooth ride and it tries to save fuel as well... so thats the reason for the delay and early shifts.. the car tries to keep rpm under 3000 with every shift and is not suppose to bury you in the seat....

its pretty much made for fuel consumption and comfort..........
