I have a 2004 MT Z with 25,000 miles. I have noticed that it idles rough at a stop. I always use 93 gas and have tried those worthless engine cleaner things that you are supposed to put in before filling up the tank. These never correct the problem. Any ideas or tips on how the get the idling the smooth out?


Thanks!

 

It's normal. The Z has a bumpy idle.

Some people say grounding cables can help but personally I doubt it.

 

Yea, I have grounding cables, they don't work, there was this huge reply and stuff about them. They are purely asthetic

 

Mine doesnt idle rough.

 

^^ they probably put an altima engine in your Z by accident =)

 

Oh man, now you've done it...You opened up this can of worms again....

 

Mines rough at times too. 04 Track bought in December 04 with only 5000 miles.

 

On no! Not the grounding wires issue. The Z's idle does bonce a little...nothing big...normal...relax....

 

i have the same issue as well, was worried but i guess i was not the only one.

 

put a power commander in it, that helped my bike with the rough idle.

 

donno if this issue only happens on AT?? or it occurs on MT as well?

 

There should be a recall on it too.

 

My Z has 29k miles now. At idle its almost silent. Even with the Injen exhaust. Also i drive it hard.

 

This isn't about sound, it's about stability. Does your idle peg at 700rpm and not waver at all? Mine jumps up and down a bit randomly.

I have an old BMW and the idle on that doesn't move at all. Pegged at 500rpm.

 

mine idled rough found out some engine mounts cracked

 

Altimas also come with VQ35DE.
