Lagging maxima
 

Recently my 99 nissan maxima hasnt been driving so cool.
It kind of feels like im driving a honda, it lags to go through the gears and then when it gets to 2nd or 3rd it jumps roughly into them.
I gotta know whats up, cause its definitely a turn off help need asap!

I can't post yet but wanted to stick this in a new post to show this. Please feel free to start a new thread. Thought you Gen 4 guys would get a kick out of it (I'm a 6 gen guy):

He said 20 t'vs, right????????????????? !!!

Sorry Mmax99.

Dont thread jack. Also, someone already made a thread about that car lol.

codes? did u do a SEARCH? Have u tried any troubleshooting urself? Do u have FSM? Cali or fed spec? We need more info here.

With what u have stated and since its a 99, i wd check coils first and prolly KS. I wd also say check your drop resistor as well

You dont have a hidden turbo under the hood that you didnt know about, do you? lol :D

is it an auto? check your fluid level/color, etc. when was the last time trans fluid was changed? (and filter)

Allz I got is jackin' till I get my 15th post. Till then, I'm in the ghetto.

Fed spec, I got the Ignition coils changed last year, broke down while at school. FML.
I dnt remember changing the trans. fluid.
sorry i didnt search lol. Felt it was too personal and depressing.
Im gonna have to check it out when i get some time. I just wanted some sort of direction. its autotragic.

i noticed in your mod's you have a wai...i'm assuming that means warm air intake.
this could be one of your problems.
with it being the summer time your engine is sucking in more hot air.

this happened to me when i removed the part where it sucks the air in from the front.
the air box was exposed to the engine heat and with the a/c on it's even worse.
once i put that piece back on, it's better even with the a/c on.

or either it's the knock sensor.
and it has been proven and said that it makes a difference.

you getting a check engine light at all?

knock sensor being bad will cause slugish feelin knock sensor will not always make the check engine light come on either get it checked even if light is not on

i think anyone who cries about this should get an auto +b this isnt soooo hard to do everyone should be giving back to the community, i just finished my 15 and its not the end of the world to do!

no check engine light at all. but ill definitely go get it checked out monday.
And yea i do have the intake attached right in the cabin.

Last spark plug change? Service Lately? Oil Change?

It could be alotta things. If your spark plug chamber gaskets are gone, oil can seep in to your spark plugs and cause this. As well as a knock sensor, broken coil packs, etc... you definitely need to at least try and pull some codes.

Im not going to read everyones posts so ill just cover a few bases.

1. Theres a link to the FSM in my sig.

2. Your issue could be a few things, but in order to find the said issue your going to need to give us the codes.

So ill say its most likely the knock sensor, if it is you could be getting no SES.

Or you could be getting a crazy amount of codes, for instance O2' sensor's, EGR related codes, or even EVAP.

So, pull the codes, post them here.

Also your tranny, check the fluid. If its anything But Cherry Red, replace it. Do Not let anyone power purge it, simply undo a trans cooler line, have someone tap the ignition and drain a **** load of fluid out of it, than replace it.

i kinda have the same problem i am going to change my knock sensor thanx guys

my 96 will take forever to shift to 2nd. and the rpms seem to jump around, i assume it was a transmission problem. I will try to replace it and change the filter as i just got it and have no idea when it was last done.

My 99' GXE seems to 'lag' around. I'll drive with constant petal pressure and it doesn't accellerate the way i expect it to.. sometimes it upshifts way too early, and i have to give it 3/4 throttle to get it to downshift again.

- I have an O2 code that comes and goes
- No mods what so ever
- 195k miles
- Normal oil changes/filter changes from Nissan dealership
