The same problems were happening with me.. I would suggest either cleaning your sparkplugs and regapping them or "whacking" the map sensor. I had both the problem of rough idle and hesitation during acceleration.. The rough idle was caused by my spark plugs being gapped too small.. I think it was running too rich causing it to foul up.. So i just cleaned the plugs and regapped them and it was fine.

 

I was just at the drive through starbucks. I had my S in neutral. I revved
the engine to about 2000RPM and it fell to about 200 RPMs and almost stalled but caught itself. I revved again a few more times and it did the same thing. After
driving away from starbucks I tried it again but it wouldn't do it.

Any idea of what is going on? I have 34k miles on my S. Do i need to change the sparkplugs or something?

 

Stay away from Starbucks.


J/K try tapping on the map sensor and also remove and reinsert it.

 

Any solution? it happens to my car too. it has 22k on it

 

Whack the MAP, reset the ecu.

 

Mine exibits the same behavior also. Honda has been working on it for 2 months. Finally, the last time I was in they heard from Tech Line that a new Service Bulletin is being released actually right now (end of Oct.) that describes the same issue and has updated parts. I was told it will have an updated map sensor and a new map sensor mount.

Ask your dealer to check and see if it is out yet.
