A Few Problems

[Curtis.Cow]

hey i have a few problems with my r33

When ever i just drive along my automatic gear box just jumps around gears, i dont have any idea how to fix this, aswell it just stalls sometimes, i dont understand that either =\

and my speedo doesnt work it just get stuck then moves back up and then back down, just jumps around

when im ideling it almost stalls then revs back up and almost stalls again

The car is running rich you can smell unburnt fuel out the exhaust, im guessing i need to get it tuned or serviced?

cheers if you can help me much appricated

throw up a list of any mods that you have to help everyone sort out what is going on.

I think the speedo is the root of the problem, might need to look at replacing/fixing the speedo cable from the gearbox. I've never encounted a Nisssan auto box so I don't know exactly how they work, ECU might be a tad confused about the current speed and selecting the wrong gears

Id say a proper service would be first on the list...its running rich because something is wrong and the ecu is adding more fuel to compensate.. how long since you changed your air and fuel filter...how old are the spark plugs ...these are the basic things that contribute to poor performance.. this is why we service our cars...if all these things are fresh...then the problem is elsewhere...maybe a tired o2 or MAF sensor or something...but if your engine is hunting at idle like it is ,,theres a good chance your torque is all over the place therefor confusing your torque converter causing your gearbox to keep changing gears...

Give the car a good service...all filters, spark plugs and oil...pretty simple really....if problem persists, see a doctor
