have a le mans sunset 2003 track with 425 miles has a rough idle was wondering if others are experiencing same problem warm or cold just rough idle

 

can you explain by what you mean by rough idle?? like the needle jumping around during idle??

 

Install a grounding kit it helps.

 

Never had idle problem (6000+ miles). Recommend you take to your dealer and have it checked soon.

it does help, or maybe Im crazy . but even so, before installing it, Im not sure Id describe it as "rough". just not as smooth as it is now(in my head right?)

Id agree, bring it in, make sure it all checks out.

 

you feel the roughness in the stick and yeah some needle fluctuation ill try the ground ing kit first what brand do you guys recomend

 

The Insaneamine Grounding Kit for the 350Z is THE BEST kit you can buy. It's $75 plus shipping. It comes in many colors and he ships fast.

the car is rwd, and nissan weighed their options, either offer bushings to reduce vibration in the stick, or not and get a tighter feel. they chose the latter, and Im glad. however just be aware that the grounding kit wont fix this, the stick will always vibrate a little bit, its directly bolted to your transmission, no rubber to absorb the vibrations.

 

yeah i just got the kit from insaneamine... very nice workmanship. Its all pre-cut, crimmped, heat-shrunk for you. Just gotta bolt it on and thats it. Haven't really noticed much difference. this might be off the wall but does the ECU need to get used to it???? Haven't taken it past 4K yet though

 

i noticed my car would misfire during idle. the dealer hooked up consult and found out that my 2nd cylinder injector was bad. i'm waiting for all the parts to come in for them to replace it. you may want to have them check it out.

 

2nd cylinder injector humm seems like everybody finds a new problem everyday oh well still love my Z =)
