Hey, if someone has access to a fax and can also scan and post the AUTO TSB that DAVEB has, then do it for all of us automatics on the org.

I just got back from bringing my car in and they said the TSB isn't applicable. I find this hard to believe since I know it does hesitate at times, more often in hot weather. In any case, they said they checked the ECM P/N and it came back alright. My car was manufactured in January '01, does anybody know when the cutoff date was for using the applicable ECM P/N? I guess for those for which this applies, when was it built? And afterwards do you still feel a slight hesitation at times? I was really hoping this was going to do it, but I guess not.

I am watching this thread very closely, becau sei have owned both a 2002 and now a 2003 maxima..
BOTH maximas's exhibit these problems both of which are 6 speeds.. I have been compliaing about this problem since JUNE 2002, which is why i really hated my maxima's quirks.. this tops the list..
Mind you, i think the main reason i broke an engine mount was because the excessive bucking and hesitation as mentioned previously... I only tracked my car once... SO i dont' know.
But i will report the 2003 drives EXACTLY the same as teh 2002 with the same hesitation..

I went to Cherry HIll Nissan and the service mgr. saw me coming and before i even opened my mouth, asked if i was a mechanic. I told him no , he said then why are you trying to diagnose problems over the internet. he didnt even want to see the tsb and said that his guys would look the car over and then if something was bad, then they would replace it. i told him to check if my maf was covered and he refused, he said that his guys had to replicate the problem. i told him that the problem was intermitten, he couldnt care less. he mentioned to me that if my car tested fine then he would charge me $84 to check the car out. oh and i have to wait two weeks for my appt.

sorry to back track here, but is my 2k2 auto covered under this, and if it is, what exactly do i tell my dealer to do?

What I don't understand is how there can be 02s for which the TSB doesn't apply, yet 03s for which it does. It would seem to me that if they fixed the problem in the later 02 ECM code, why would the 03s carry over code that still had the problem? From a code development point of view it doesn't make any sense. In any case, I'm confused over this. I was really hoping this would apply, but I have no reason not to believe the dealer since they actually seemed to be pretty cool, actually listened to what I was saying for once. Does anyone know if an OBD-2 tool is capable of reading the ECM P/N and ID?

I thought the hesitation was a pause before any noticable acceleration was felt. I have no experienced this.

However, tita6 is saying that it's the bucking you experience while letting up on the gas in 3rd gear. My car does the same thing as Chinkzilla is describing here, which is bucking while in 1st or 2nd gear, cruising the parking lot or rolling slowly in traffic. This usually happens when I let up off the gas completely, or almost completely. It starts jerking, and I have to apply gas to smooth it out.
If the latter description is the lag that everyone talks about, then I'm thinking a lot of cars have this problem. A couple of my friends have manual cars (Lancer OZ, and Ford Focus), and they both do that in low gears, and I'm pretty sure they don't have DBW. I've also read about this bucking on other car forums, and it seems like this is the nature of the manual beast. I was under the impression that all manual cars behave in a similar manner.
Can anyone enlighten me on EXACTLY what you guys are talking about in this thread? How can I try to reproduce this lagging effect? My car doesn't seem to have any, but maybe I haven't tried to use the right "setup" to experience it.
Thanks.

I guess I don't have it. I'll keep trying to reproduce it, and see if anything happens.

Update:
I got the car back Fri night. It did seem smoother with almost no bucking. Also, I thought the wind noise TSB did make a difference. Saturday night I was cruising with my lady and we pulled up to a light next to a BMW 330 on Rt 28 at the Dulles Golf Center. I don't think he was ready, but I was so I launched hard (no hesitation), pulled several cars on him, then missed 3rd gear, went into 5th. He started trying and caught me as we pulled up to the next red light.
This time I knew he was ready. We both launched hard, me with only a chirp. I pulled 3 cars on him by 70 and held that until I let off about 110. I kinda thought he would start to walk up on us but he didn't. I went West on Rt7, he did the ricer flyby and went East. Don't know if he was auto or manual, but I'm sure he was ****ed even though I chose not to hit the flashers.
Needless to say, I was pleased with whatever they did to my car at Rosenthal.
Anyway, jump in ride Sunday afternoon and BAM! SES! She's back at Rosenthal right now. I can't wait to hear this story.

Man this post is long. Does anyone have the the name of this "Update", that I can fead my dealer so he can fix my hesitation problem. Hesitation being, when i press the gas, there is a delay before it goes. Regardless of gear.
The lagging bopping when u let off the gas is typical in almost every manual car. I have had 5 in teh last 10 years. 4 of them proudly boggled alot, the 5, well, lets say, it wasnt near as bad, but it did it. Nature of the beast. VW's are least likely to do this by the way, dont ask me why....just added 2 cents.

Check the sig. I do have HSLD.
The car is at the dealer right now so I can't be sure fo the manuf. date. I had to order it and I picked it up in early March so I think the manuf. date was 1/02.

Ok I just got back from the dealer, had it done this morning….. They had no idea what I was talking about so I gave them a copy of the Service Bulletin they mad a copy of it. About 2 hours later they call me into the service dept saying the tech is done. He said the tech didn’t change the MAF but did reprogram the ECU. I can’t say that I felt the hesitation that many had complain about, but I can say that there is a slight difference in the car. It seem to be a little more responsive from the slightest pedal movement, It could be all in my head but like I said before I didn’t feel a problem to begin with, so the slightest change that they made was felt.

So I call the dealership On today to set up an appointment for the TSB on my 2k2 Auto. Dealer tells me that they won't just do the TSB if I have no problems with the car so I tell them the car hesitates and he reluctantly schedules me an appointment. After pondering a few moments I call back and ask (anonomously)if having an aftermarket intake and exhaust would void a warranty, he suggests removing the items before coming in. Is there any dealership in or around New Mexico that won't cry about after market parts and just do some freakin work? Why is Nissan or this dealership so picky?

Where is the ECU located in the Maxima? I have a 2002 6spd but I would like to see if my ECM P/N matches the one on the Service Bulletin. I don't want to make an appointment and get angry or upset if I don't have to. Needless to say I am trying to be proactive. Any insight as to where I might look would be helpful....
