Idle Problem.. does this sound right
OK I have been having idle problems for a while now (2000 Civic SiR).
First it was idleing low, so the dealership replaced the IACV (idle air control valve). Problem wasn't fixed. Next I cleaned the black carbon buildup in the throttle body with some throttle body cleaner. My idle was just about perfect and I noticed that the throttle (gas peddle) felt like it was sticking at the very top, so I had the dealership look. They cleaned the throttle body again and said that the throttle body was pitted. After this cleaning it seemed to idle higher then normal when worm (between 1000 and 1200rpm) and after driving it for about 3 hours with lots of start and stops, the engine light comes on and the tach is stuck at 1500rpm. When I go to step on the gas and let out the clutch the car seems to hesitate ALOT. When the car is truned off then truned back on the idle jumps from 1200rpm to 1500rpm a few times then settles at 1200rpm.... after driving (start and stops) a while it returns to 1500 and hesitation. My question is, Is this anouther faulty IACV? Would them "cleaning" it have done something to it? thanks for any advice dave |

My evil eye is settling on the throttle body, since this got worse after the dealer had a go at it. The butterfly may not be closing all the way as a result of friction, or something may have come loose. The dealer should get first chance of making it right, and they should be accepting the look-see as a no-charge follow-up (love those hyphens!) to their work. No professional wants to lose an opportunity to correct any mistake he may have made. If you get no satisfaction there, I think you may as well have a look at the throttle body again. It's possible the throttle body is not going to work reliably because of the pitting (corrosion?) they described. If that's the case, I suggest beating the bushes for a throttle body from a wrecking yard. There have to be *some* around for a 2000. The "check engine" light is almost certainly in response to whatever is out of whack and I doubt the codes would tell you anything you don't already know. When the symptoms are fixed you can worry about clearing the light... it should clear on its own eventually if you are patient. Mike |

Re: Idle Problem.. does this sound right
Thanks for the replies.
Sorry I forgot to mention the code. It is P0505 and in the manual it says could be the IACV or Throttle body at fault. dave "TeGGer®" <tegger@tegger.c0m> wrote in message news:Xns9638CD718A84Btegger@207.14.113.17... > "JEHU" <dcoxNOSPAM@hfx.eastlink.ca> wrote in > news:XSy7e.31021$vt1.15636@edtnps90: > > <snip> > >> the engine >> light comes on > > > So what's the code?????? > > We NEED to know this. > > > -- > TeGGeR® > > The Unofficial Honda/Acura FAQ > www.tegger.com/hondafaq/ |
