Does anyone have a problem with their coupe and uneven idling? When starting my car, or coming to a stop from driving I can hear the car idle unevenly. I don't know if it's just that I can hear it better than my honda civic, but it has small variations in the idle...does anyone else have the same problem??

 

kinda happened to my car when i first got it.
when i'm stopped, the needle sorta jumps around, so i took it to the dealer and fixed it. something about a sensor they had to adjust.

 

every VQ based car I've been in tended to lope alittle.

 

hmmm..well, at least it ahppens to all of the cars with the same engine in it..It's not a severe as the needle actually moving around, you can just hear a very subtle uneveness or jump in the idle when at stop lights, etc...Does everyone else have this problem?

 

Even idle on my 04c AT. My G actually idle just over 120-150 rpm, pretty low but it never stalled. This was after installing 6 grounding wire. Maybe that can help.

04c, Black, AT, PIAA, AL padel, smoked clear corner, 6th grounded-wire, z-tube/pop-charger, Data grille & Gialla spoiler (on order)

 

My 2004.5 5AT, completely stock, with 1200 miles on it idles smoothly, with no fluctuations, right at 500 RPMs where it should be, with air condition off and engine at operating temps. Yours should do the same. Take it in for service. Could be a sensor, could be a hose, who knows....let them sort it out.

to clarify, my needle is smooth. but I feel loping.. I fought the Nissan dealer about it when I had my maxima, showed receipts for prem gas, new coils/plugs, you name it.. Gave up.

With the GC, I drove some G35S loaners, all felt the same.

BTW, your tach starts at 500, so add whats above the first tick. That puts mine right at 700-ish. Doesnt fluctuate (other than warm vs cold).

 

Mine does it as well. Sort of skips a bit at idle, but tach dosent move at all. Dosent seem to be causing a problem though..

My G 6MT does the same thing. The tach needle stays exactly at 700 rpms and I do feel the engine loping. The dealership stated that they could not 'duplicate' the loping. What B.S.

 

Ah, I see what you're saying. It starts at zero but the first tick mark is at 500. Yes, mine starts at 1300 cold and gradually works its way down to 700/750, I stand corrected.

But I feel nothing but smooth idle. No loping, no missing, no fluctuation whatsoever. It's weird that your tach stays smooth and fixed, but you still hear fluctuations.

Yea I have this idling issue too. I mean the needle doesn't jump around or anything but I definitely feel these freaking vibrations that are annoying the hell out of me. Anyone got any fixes for this or what?? Is this normal? I have 7800 miles on right now

 

i think u guys are feeling the tranny under your seat if u dont see the needles move at idle.
where are u feeling the vibrations?
seat, floor, clutch, shiftknob?

 

Not feeling a vibration, but I can hear the engine surging sometimes at idle. Like an old car with its timing off.

exactley like an older car might do...It sounds fine 95% of the time, but if you sit there and listen to it it will idle perfectly for 20 seconds and then have a small blip of uneveness for a split second and then it goes back to sounding regular. Think of someone singing a constant note for 30 seconds..in that 30 seconds the person faulters for a split second in their pitch but then continues to hold the tune..I don't know, that's the best way I can descibe it. Just like an older car kinda..The tach does not move at all, I think it would be too small of a variation for the tach to move..
