maxima_tyler

any engine light on? if so find out what the codes are.
if no engine light, maybe it just needs a good tune. spark plugs, seafoam and an oil change.. its a 12 year old car so theres bound to be some carbon build up

vip_usamamu

Hello thx for reply there is no any engine light on and evry thing normal

By torque are you refering to the power not getting to the wheels but the engine reving?

maxima_tyler

it sounds like (to me) that everything is running smooth, but there is a lack of actual power. thats why im suggesting a good tune up and seafoam to clear out build up and whatnot.

with no codes, its hard to tell.

OP when you replaced the coils and MAF, were they with Nissan Genuine Parts? if they are aftermarket, perhaps even though they are working, they may not be working to oem standards...?

vip_usamamu

Maybe you have bad catalytic converter/s? Those clog up and makes you lose alot of power. (i dont know if your country has them) If you do gut them out see if it makes a difference.

p.s. that brake fluid is very black.

vip_usamamu

Thx alot but what is*catalytic converter ,?
Which part u mean

coolsun

iTrader: (10)

it has to do with the exhaust. It helps with air pollution, there might no be any pre catalytic converters on your car but im not sure until you look at it. There is one located in the front header/manifold and one in the back which is fat under the heat shield. I am sure you have a main catalytic converter towards the middle/rear of the car.

this is not always a cause of a power loss, but if the car has alot of miles on it, i would suggest gutting these if you have them.

the right side pic is the one with the cat, the left side is without.

vip_usamamu

ah i understand u. this parts its for catback and connect to out smoke of the engine to send back side and give car more power but i dont know which part i has so i need to up my car when i wash and take aphoto and i will post here but one more question this actual power only one pipe other car 2 pipe what is deference . is this give car more torque ?

the catalytic is so your car dont make dirty smoke out the exhaust, but can give you more power if you gut it out, not alot but alittle difference

vip_usamamu

It's not a racecar. Looks fine to me. Seems as if maybe you're overreacting a tad? If you feel so inclined, check the VIAS cup. Also, removing an air filter isn't going to make that much if any of a difference.

vip_usamamu

im taking about racing cuaz show much power car have i need only car fast respond i feel car lazy

do u think this device can solve my problem

im pretty sure that device will not work for the maxima.

maybe you have a dirty throttle body? start modifying the car?

vip_usamamu

i read there is maxima coming 220 hp and 230 hp if my car 220 hp it will be this big defrant ?

i read also this ECU need to program or can change hp chip is this correct ? to increase power ?

Im pretty sure it will not work at all. There isn't any real plug and play chip to increase power out there.
