I know there has been a few posts about this a year or so ago.

My tachometer will slowly creep up from idle to full RPM over the course of about 40 minutes to an hour. It does this regardless of actual engine RPM. I know a few others a while back have reported this same problem.

Has anyone found a fix for it yet? Kinda sounds like a grounding problem to me, but I'm not sure exactly how. I'm worried it could be a computer issue. Obviously its not a sending unit, because the engine runs fine. Any ideas?

BTW, its a 96 Maxima. Thanks all

What is full RPM?

 

I was told by the stealership I needed a whole new tach. I said, thanks but no thanks. I like redlining all day long.

 

sounds like u need a new tach. 97's seem to have a problem with the speedo...i am getting my replaced as we speak....count on it being around $400

WOOW i have a similar problem , my rpms are fine at idle but when i drive sometimes they dont even move, my motors runns fine and it starts to work after driving on the highway for a while or if i drive at high rpms, iv'e had a couple of cheap machanics and friends look at it and no body knows what this is. i didm't think anyone else had this problem. one of these days me and my boy are gona switch clusters for a test to see if its my gauges or something else. Has any body ben to the dealership with this problem?

 

New Tach... what do you mean?

you mean the actual unit in the gauge cluster in the dash? How can you replace that? Don't you have to replace the entire gauge cluster or can you swap a tach unit in there?

Anyone with this problem already had it fixed? Does replacing the tach gauge solve the problem? Also, anyone have any leads on a new tach?! I love the car, but I'm not gonna shell out $400 on a needle to move that I don't absolutely need!

Anyone disected a tach and found out what the actual problem is? Could I pull it out and re-solder something?

Thanks for the great help all. Rock'n Roll

Sorry, I don't remember what the mechanic called it the actual part. It was a few years ago they looked at it. It had something to do with the tachometer. It definitely wasn't a whole new cluster. Part was only $150-175.00 range. I don't think it makes a difference, but I'm a 96, maybe parts are a little different? Sorry I couldn't be of more help. If you're in AL, I was at Dyas Nissan in Auburn, AL. Here's there phone number.(334) 821-4888 Give them a call, maybe they know something other mechanics don't. Good Luck.
