My car idles very rough.. You can feel the steering wheel shake and it starts to pulsate.. I just purchased this 04 350z Roadster 5a/t
The motor runs super strong, and it doesnt really have any issues aside from the rough idling.. I tried to relearn the idle by following the procedure, but no luck.
Does the dealership have a scanner they can use to relearn it for me?

 

i'd do a compression test and a leak down test.

 

IS you idle lower or higher than normal? If not, then the relearn probably won't help.

Did you try all three procedures?

If not, read this... https://my350z.com/forum/engine-and-...procedure.html

 

Yes the dealerships do have the scanners to relearn idle if that's what u think ur problem is.

 

You can relearn the idle yourself by disconnecting the battery for ten days. If you're really concern, I would just bring it to a shop/dealer that knows more than you do and let them deal with it. If they cannot, test drive another vehicle similar such as yours and compare. Perhaps it's normal and you do not have to disconnect the battery for ten days.

 

ive driven quite a few different Z's
This one's idle jumps around.. it will be fine for a few moments and then drop n want to stall..
