idle unstable 2005
2005 150k
vehicle had jutter, slip and idle issues.
after burnish the clutch, jutter and slip went away, but idle problem remains
before burnish, idle would consistently bounce at stop w/ AC on
after burnish, idle seems much better, but sometimes at stop w/ AC on, the idle will go down so far the vehicle will stall
any ideas?

Re: idle unstable 2005
Does it just do it once while warming up? When my car goes from open loop to closed loop the RPM drops briefly quite far and then recovers. It only does that when it is warming up, once it has gone closed loop it will not happen again (on that trip). With the A/C on I would guess the drop might be worse. However, I only experience this (usually) going to work in the morning, because it happens mostly at the same long stop light. It isn't hot then so no A/C on. Coming home the car makes that transition while moving at 30-40 mph and nothing is evident.

no, idle problem happens at start and later during stops.
shop says they tried IDLE RELEARN procedure a couple times, but are getting info of a MAP SENSOR failure.
next is replace MAP SENSOR and try IDLE RELEARN again.

Re: idle unstable 2005
I had the same issue, where idle would drop and almost stall, but never did, as well as it wavering about (see a video here). I've done about 3 gas fillups adding a bottle of Chevron Techron concentrate each time (for one of the treatments I added it to a quarter tank of gas and drove it before filling up), and also used a can of Seafoam spray through the air intake. This seems to have mostly eliminated the issue. I believe the seafoam spray is really the key because it cleans out the throttle body which is where this kind of problems seem to come from but I can't be sure, it may also have been gunk in the fuel-pump which the techron helped clean out. I have an outline of these products on my page: http://hondacivichybrid2.mooo.com/#engineperformance
Might be worth giving it a try.
