99 Stalling but completely different then the 98
Hey guys i have a 99 accord v6 with around 130K on it. EGR was "serviced by dealership." I have a warm idle problem. So when i start the car dead cold starts right up and runs great. When the car is in ANY gear it also runs perfect regardless of temperature. However, once the car is warm and i either ut it in neutral or park, or i restart the car before it has completely cooled off it will go down to about 200rpms then try to cycle up to 800 then back down to 3-400, then back up and hunt for a few seconds. It normally then settles into its normal 800 rpm idle however last week it actually stalled a few times on a really cold day when he engine was warm and i had to try restarting it like 3-4 times before it worked ok.
I would really appreciate the help guys? I did a search but dont see any v6's with my particular symptoms.
Thanks

I have seen about a dozen V6 accords 98-02's that have a hot soak problem like this. It will start and run fine cold but after it's warm and you shut it off for 10-15 mins. it will die and run like crap when you start it.
We tried everything to fix it, EGR, injectors, ECU's, Valve adjustments, Coil packs,Fuel pressure regulators, etc.. Honda's factory techline told us to replace all these parts and still the cars have this problem. From what I've been told the fuel is vaporizing in the lines before it gets to the injectors when the car is warm. Techline gave us an "unofficial fix" for now which works ok but it doesn't fix the original problem just fixes the symtoms.
What you do is take off the power steering pump, directly beneath it there is a two pin connector that is secured to the engine. Unconnect it and jumper the pins on the female side going to the ECU. reassemble the car. The problem will be gone but the fans will run for 15 mins EVERY time the car is shut off. It sound crazy but it works perfect. I'm assuming that the fans keep it cool enough so the fuel doesn't vaporize before the injectors...
