Saphier, you seem to have TWO problems. The first is most likely instable voltage. Try gong to DIY car wash with a can of GUNK orange and power wash the entire engine bay Focus on the alternator, the battery and the battery cables. If you see any green corrosion around the battery, then have your battery posts brushed and cleaned. This will give your charging system the oomph it needs to supply ALL the necessary voltages to ALL your cars electrical systems. See if your valve cover gaskets have been leaking any oil onto your alternator. If it has, then try tightening the screws down a little bit. THE MOST COMMON reason for idle issues and unexpected shut downs is a dirty IDLE AIR CONTROL VALVE. What happens is that regular dino based oils give off a sludgy vapor that recondenses on this valve and the thtrottle body and also in the PCV valve. A can of GUM-OUT will get the muck out of things and return things to NORMAL. You should consider using MOBIL ONE or other fine synthetic oil and replacing it once a year. Make SURE that whatever oil you are using has the name Honda on it's label somewhere and stay away from oil change SPECIALS that are using oils with NO ratings for ANY car maker. Your car will love you for it. Your engine was designed for the exclusive use of synthetic oil, anyways. So now you need enough money for a $10 worth of cleaners and an oil change. Never be afraid to actually look under your hood. You will have to remove the long rubber snorkel that leads to the IAC valve to get it clean. A phillips screwdriver is ALL you need. GOOD LUCK!!
