Recently.....when i come to a stop light and am sitting there for a few minutes.....the idle will bog a couple times....and it feels like someone has just tapped the rear end.
It only does this when at a stand still, with the brakes applied while in drive. If i put it in neutral it doesnt do it. I haven't checked to see if it does it in reverse or 1 and 2. No problems at all while driving.
Does this sound like a tranny problem......or could it be something else?
Nissan put in a brand new tranny back in '96 @ 20,000 miles. The car has about 140,000 miles on it now.........so roughly 120k miles on the new tranny.
Thanks for any info

 

there was a huge thread on this that died a couple weeks ago, it was like 2 yrs old. no one knows what really happens. i have a 5spd so i dont really know

 

Not really helpful...........but thanks
anyone else have any ideas??

 

Sounds like what happens to my computer, except I think that I don't think it's a tranny problem. My TB or IACV might be a little dirty and the idle gets too low and stumbles a little when it's in drive. Try cleaning your TB?

 

hmmmm, the problem actually started after i cleaned my tb.....not right after......but within a few weeks. Maybe I'll try cleaning it again....thanks.

 

Misfire?
Could be coil packs on the way out.

 

i've only noticed the problem while idling in gear........park or neutral it idles perfectly fine as always. I'll let it idle longer....and see if it does it in neutral or park.

 

My old car used to do that.... I let it do it for two years till i sold it. I wouldnt worry bout it as long as its doesnt occur daily

 

thats the problem............it does it anytime i idle with it in gear after a couple of minutes. it will do it like 2-3 blurps every 2 minutes or so

 

Thats a misfire. My 99 started doing that, only felt it while it was in Drive. I had to replace ALL of the coil packs to get it to stop. It never threw a code and only did it once the engine was warm.
