Hi guys

Few months back my car started having a low idle resulting to a more and more shake of car.
Its been back to Honda 3 times and they claim nothing is wrong and reset the idle they say, its somewhat better but in weeks time I'm back to square one.

Anyone have any clues?

Idle is about sits at 650rpm fully warmed up.

Also I noticed auto sometimes shift to a hi gear when it should been in lower, hope nothing relating to idle issue. Ie.gear 5 when it should be in 4th

 

I've noticed mine idles a bit too low making it a tad rough as well

 

I might try these...seafoam worked wonders in my Mini Cooper S

 

Mines only done 39000 km wouldn't think would be that bad.
Where sows everyone's idle sit at?

Maybe I should try changing plugs ?

Somehow I have a bad feeling might be tranny related.
When I dropped the car off last time they noticed my tein as coilovers they tried the old( oh its your suspension) lol

 

I just got my 2011 TSX wagon and it drives great but does idle a little rough at stop lights. Mine has 18k mi on it but my old 1995 E320 wagon inline six was smooth as butter at idle and pretty much at all speeds. The TSX is much better fuel sipper but it's a bummer with the vibration at idle...it's better in Park.

 

No nothing yet. I'm due for service shortly so will take to different dealership, will keep you guys posted.
Berry rice where does you rpm sit in drive fully warmed up?
