hello everybody....i had a problem a few weeks ago...my car was stalking and then turns off...so many said to replace the MAF sensor. so i did...and the problem was gone....but....of course....there are other problems now. i have a very annoying sound when i start to acelerate...sounds like something on the mufer, or like a lose house (i really don't know haw to explain that one). when i start the engine before was a smooth sound, and now is diferent. also when i acelerate its nat smooth, sometimes is a problem to acelerate, start to pull back somehow (thats haw it feel). and it's spending more gasoline than normal...
any ideas......i thought that it's again the Maf, but i don't have any cel light on..
please guys....help me...

ok...si hay alguien que habla espaņol...aqui le va mi problema...
1. Mi Maxima tenia el siguiente problema - el auto no se podia acelerar y ciando lo hacias simplemente perdia fuerza y se apagaba. eso desde que lo compre. el foco de Chek Engine estaba prendido y sacamos codigos...fue Knock sensor y Coolant Temp Sensor. Los compre usados, los cambiaron y el problema no desaparecio, pero el foco del Check desaparecio. Estaba igual. no se podia acelerar, llegabas a 40 Millas y se jaloneaba, y se sentia que se ahogaba el auto. Mi mecanico lo reviso varias veces, se cambio filtro de gasolina, se limpio el Trottle body, se cambio IAC sensor, de nuevo el Coolant Temp Sensor y finalmente le cambie el MAF sensor. Entonces ya el auto dejo de apagarse y se maneja basta bien, pero en todo......
2. Ahora tengo un sonido desde el area de motor, se presenta cuando acelero y especialmente cuando estoy subiendo....el sonido es como que tienes una manguera y esta saliendo aire, pero ya cheque y no tiene ningun escape.... el auto no acelera bien, se jalonea de nuevo..pero no tan fuerte, la aguja de los revoluciones a veces esta bailando de arriba a abajo (eso no creo que es normal) y cuando prendo el auto el motor se oye muy pesado...antes la maquina era muy suave, casi no se oia, ahorita es un ruido mucho mas fuerte...
tambien se le hico tune-up, cambio de filtro de aire, de aceite, aceite, bujias y cables. pero eso hico el problema nomas mas grande..
si alguien puede entender eso, le agradeceria muchismo su ayuda....

 

check your hoses make sure they are all connected.

 

from one girl to another ---

now, the guys might laugh at me cause i might not know what im talking about, but what i think is this:
your exhaust really has some effect on your gas milage, that however shouldn't effect how your engine sounds, but it will cause some "knocking" sounds depending on where your muffler is 'leaking' at. About the pulling back, I dont know ... I would think though exhaust might have something to do with that, it might studder a little bit.

I am just trying to help, if I am wrong, I will get laughed at :P But, thats what I think it might be since you said your muffler sounds different and your having gas economy issues.

Hope that helps

If not ... I'm sorry

 

Check all your hoses connection...you might miss a hose or two....plus trace back to how you took the MAFS off then put it back on the same way.

 

hahahaha best way to get help is inform everyone that you are a girl..

 

It's the best way to get replies to your thread, but not the best way to get real help.

 

OMG...stalking, mufler, house, lose, nat, acelerate, haw

 

WHAT IS OMG?

 

dang.. looks like the female community is growing

 

oh, my, god, becky....

 

Tks For The Clearing That Up

Anybody Else......ideas....???

 

no, that would be OMGB

 

Well you could always bring it by and let me take a look I live in SD also and no im not trying to hook up with ya OK lets clear that up right now

 

I LIVE IN TIJUANA ACTUALLY, BUT IT'S KIND THE SAME.....
AND I CAN DO THAT....TKS

 

lol yes you are lol. J/K

Like how diff. does you engine sound? High pitch like you're excellerating ? What does it sound like exactly?

 

OK. I WILL TRY TO EXPLAIN MYSELF...SO BEFORE THE ENGINE SOUND WAS LIKE MORE SMOOTH...i didn't look sometimes like you it was on...if you what i mean....and is like more excellerate like you say...and teha car is shaking a little.
i don't know haw to explain this...sorry

 

I'm not sure people can understand you. Reread what you type before you post..too many errors to even understand.

 

yeah i know....not my best english....

 

Yea just let me know when you have some free time to come across the border. no pun intended. Im pretty busy during the week but im free during weekends,. And no im not trying to hit on her I have a gf unlike most of the saps on this forum

 

rofl,

 

i usually cross the border on sundays so if you want you can write to me on my e-mail..i post it here..or vs. let me know

 

a vacuum leak could make the car run rough. There are 3 hoses that connect to the intake tube, between the MAF and throttle body. check them. also maybe you didnt get a good seal between the new MAF and air box. also the box may not be closed all the way.

Check the codes just to be safe, some problems dont light the CEL.

but maybe you have another bad MAF?

 

If you think the noise is coming from thr exhaust, check the Cat, that could make a lot of "rattling" noise when accelerating, if I'm describing it right. It also affect greatly the gas mileage. Worth a shot to give it a check.

 

Ohh its a gurl.. lemme drop everything in life to help her..

 

I would make sure all the Hoses and also if you unscrewed the 4 nuts that hold the MAFS for any reason you might wanna ensure that they are tight enough to avoid any leaks. I recently had the same symptoms like you explained above. I went back and tightened the 4 nuts and bingo...no noise no stalling. Hope this helps.

What are we comming to guys,
if you can explain a little bit better maybe we would actually be able to help you, lol.

 

I WILL TRY WHAT HE SAYS AND THEN GET BACK TO YOU...TKS

 

Heh, heh...

This post belongs on FC.

I call troll.

 

Yea i'm sorry, maybe someone can meet you in person and that way they can have a better feel of whats going on with your engine there.

 

wow, half of these replies are not even helping, just bumping thread up.

Sorry, i dont know how to help you

 

Great thread...

I just get a good laugh reading it. I don't think I can help.

P.s. bring it to your local mechanic and have it check it out.

 

Yea right the local mechanic were she lives may have it stripped down lol

 

If your in TJ im guessing you speak spanish, tell us what it is doing in spanish and maybe someone can translate (not making fun)...= ]

Good one. i dont know if you meant anything by it, but i translated it differently! haha.

 

Hell yeah, I understood it a lot better. Now you will prolly be able to get some help

 

glad im not the only one.

 

Right on.

I wish I knew how to help her ......

at least now we know why the english wasnt the best (no offence hun ... but you speak better spanish and thats not a bad thing at all!!)

I really hope that didnt come out offensive......

 

true. if you want, you can type the problem in spanish. i am actually Korean but born and raised in brazil for a while. so i can translate spanish pretty good. that way, you may be able to get some help.

 

Uhhh... Maximus_95, see post #34...
