I had the clutch replaced 2 weeks ago. Afterward when i accelerate hard the car surges real bad and makes a popping noise kinda like a back fire but i sounds like its comming from the trans. so i decided to take the trans out and have it looked at. Well the shop called and said their is nothing wrong with it. So does anyone have any ideas on what it could be or suggestion on wat i should check? Thanks for any help you guys can give

 

.. i have 98 nissan mexima ...recently having a problem which is when i press the gas paddel the ramp gose over 2.8 but the car doesnt seem like kicking up the speed like the way im pressing the gas paddel ..its seem like going and then give a kinck and bhom runs allright. its seem like someone puling me from back and then letting it go.pluse its bivrate and make wired noise more bivrate on reverse..my questions is why its doesnt pick up smoothly? or why the car doesnt run to the minimum speed? what could be the problem and what is the sloution? thanks guys

 

Newton, what you're doing is called thread-jacking. You're asking questions in someone else's thread. Stop it, I've seen you doing this twice already.

Bump for you tcrow31, wish I could be a helper

 

Thanks dude

 

have to bump

 

Auto or Manual?

Light load or heavy load? Does it buck at a particular RPM every time? When the car is cold or warmed up, or both?

Dave

 

I have this 96 nissan maxima right, and it got into a minor car accident, the car was driving fine, drove back home and around the corner when i had to move it. I bought a 97 maxima so the 96 been sittin for a few weeks, back tire went flat, and the battery some how died. anyway when i went to jump start it, the once quite *** engine makes this really weird funny clankin noise like something is really wrong, the oil is old and needs to be changed, do you think this might have something to do with it? please get back to me i dont wanna move it with it makin all that noise.

 

What do the moderators say around here about newbies that hijack threads because they can't search, can't post, and can't PM?

Dave

 

what are you talking about dave, your the one needlessly posting to my reply, i can see if you enlighted me with some advice, but your doing more harm by cristizing me for no reason, you dont know if i been looking around, you dont know anything. dont reply if you dont have anything better to say but critisize. I aint trying to be no annoying person. your annoying me.

 

I do not see you lasting here very much longer ...

 

1) I was actually wondering to the moderators what privleges newbies have (does the search now work for everyone? If so, that's good) and openly asking if it contributes to newbies acting in a more inappropriate manner. I was not talking to you at all.

2) You want to know annoying? Try this: http://forums.maxima.org/search.php?searchid=333408

3) You want to instigate me? Good luck little child. Hitch your diapers up and get lost.

i cant access that. perhaps i am to new also. or when im not so poor i'll buy my freedom on the org.

btw..if the mods are watching, how do i fix the thread clock, mines still an hour off since the time change?

tcrow31...you need do be more specific about your problem so we can help.

 

I'm still trying to figure out what bivrate means.
Seems they don't teach english in Brooklyn these days.

 

vibrate????

 

First of all, Newton. Please review your spelling before you click post. Its hard to understand what your asking. Also, if english is your second language, then I am an ******* and you need to go learn more.

Second, don't hijack threads because you may or may not have a similar issue. the search function, as far as I know only works for people who have donated to the org. That includes the "see other posts by the user" as that does a username search. To cap things off, and since the 4th gen forum is full of post hungry ****** anyway...if you have a question post a new thread of your own. We see enough posts that ask the same thing everyday to look past it and maybe only ***** a little. Now I know there is a waiting period or a certain number of replies you must get before you can post your own, but rather than being a newb and hijacking just reply saying, sorry I just got my maxima and I have no idea what your problem is.

Tcrow31 - I don't know, maybe you should have the trans looked at by another shop to get a second opinion. Also, does it do anything like this when you accelerate normally?

 

Its a 5 spd, It does it moderate to heavy load and it does it both hot or cold. Their isnt a particular rpm it does it and it doesnt do it all the time but it does it quite a bit. I wonder if it could be the knock sensor or crank sensor retarding the timing and i dont have any ecu lights on.

Tim

 

Your the second person thats tried to hijack my thread. For you and anyone else that is thinking of hijacking me donate 20 bucks like i did and create your own thread or use the search

Tim

 

does the ecu light turn on when the car is off in acc.? i thought mine was fine, but then again i didnt even have a cel bulb in the cel spot. there could be a bad sensor, not sure which, and you might not know cus there isnt a light that can turn on

 

try a good fuel syst cleaner, try checking your mafs. make sure its plugged all the way in and wiggle the plug a little. pull the airbox lid and maf off and check for dirt or carbon on the mafs screen. try to see if there are any other symptoms like bad gas mileage, exhaust smoke, fuel smell....things like that. maybe we can narrow it down a little.

 

I never thought to check to see if there is a buld in i. I will check to see if thats the case

 

this all started 2 weeks ago right after i got the new clutch in. The car ran fine before hand. I took it back to the shop and they said the clutch is fine. I thought the diff. bearing were going out so i took the tranny out and took that to the shop and they said there is nothing wrong it so as soon as i get the tranny back in friday ill check all that.

Tim

 

Only moderate to heavy normal driving is fine

Tim

 

so on a whim that the diff bearings might be bad you took the tranny out?!
wow...

 

But there could be codes stored that don't trip the CEL. Pull the codes to be sure.

Definitely remove all grounds on your tranny, wire brush them, and refasten them. Also check your crank sensor which is easily damaged when dropping the tranny.

If that's all good, I'd look toward ignition or fuel (plugs, coils, wires, injectors, fuel pump). Hard to say which, unfortunately unless you can plug into the exhaust with a wideband and read if it goes rich or lean during the bucking spells. However a fuel pressure gauge isn't too hard to find so you could at least test the fuel pump.

Finally, be sure there are no important wires that could pinch or pull tight when the engine twists in the mounts.

Dave

 

Yea well when i had the clutch replaced i also had a leaky CV shaft seal and i read the stickies on 4th gen trannys. So i figured why take the chance on in locking up and costing me more money to fix. Besides the trans was suprisingly easy to take out only took 3hrs

 

How can you check to see if the crank sensor is bad or not. I also noticed alot of medal shavings stucked to the tip

Tim

 

Sorry, I was confusing the crank sensor with the transmission position sensor. I think they are generally unrelated. However, if you see metal shavings in the oil when you remove either one (was it the engine oil or tranny oil?), there is definitely a problem. Get it diagnosed - this certainly could explain the problem. And take it to a different shop - if the tranny shop told you a tranny with metal shavings in the oil is "good", you might consider reporting them to the BBB.

In case you want to check the crank sensor, it's in the EC section of the factory service manual. Also check out page EC-83, with the symptom and component matrix.

Dave

 

I think we're both confused. ummm let see if i can describe it. The sensor im talking about is the one on the front that goes between the bell housing and motor and the 2 prong on the tip of the sensor straddles this wheel with teeth on it behind the flywheel. Tranny was clean and had no metal shavings

Tim

 

Some shavings on the crankshaft position sensor in the bell housing is normal. Just clean it off and put it back. Make sure you pull and clean the other crankshaft position sensor (located right below the crank pulley on the passenger side of the bay) and also the camshaft position sensor - located in the timing chain cover right above the accessory belt pulley/tensioner (one 10mm bolt IIRC holding it in IIRC).

 

also, double check your grounds when you put the trans back in. i remember reading in a thread..blackmaxx????too much and still not fixed??? there were similar problems. something about a ground contact point between the engine and trans where the two meet. i'll search around to see if i can find that thread.

 

heres blackmaxx96's thread. not exactly your prob, but it all started after a trany swap. maybe he can help.

Funny thing that you mention grounding straps cause i didnt have to take any off when i dropped the tranny not one i wonder when the shop did the clutch job they didnt put any of the grounding straps on. Does anyone know how many grounding straps and where they go?

Tim

 

bump bump bump

 

alright just an update on the situation. i got the tranny back in friday and i've been driving it for 2 days now and so far no problems. the only thing i did differntly from the shop was connect this ground wire to this brass terminal connected to the trans housing. i guess i will have to see if the problem reoccurs later on.
