idling drop to almost zero when shifting to neutral

[aliaga]

Hi,

I'm having a problem with my civic 2005, idle is dropping almost to zero when shifting to neutral then it will back again to normal. I have already replace spark plugs but the problem is still there. I know that the standard idling is in 0.8 or below 1. Problem is not consistent. there are times normal and not.

The only additional accessories is my subwoofer and ionizer, does these devices cause the problem?

Your comments and suggestion please.

Super thanks.

civic 2005? medyo bago bago pa ata para magkaron ng idling problems ah. well anyway, basic check up for idling problems is IACV and throttle body cleaning. well, if we are going to analyze, if ever yun nga ang problema, most probably hinde ito nalilinisan before kaya nag build up na yung dume...

the 2 links above are write ups on IACV (idle air control valve) and throttle body. if you want DIY, you can search the net and forums for a step by step procedure. madali lang yan. baka sakaling yun lang ang madumi. you might as well check muna yan before mo dalin sa casa o talyer na nananaga ng presyo.

hope this helps

just to add.. the IACV sometimes called servo

Actually sa CASA ko nga dinala pero negative pa rin yung result. Works done was Clean Body Throttle and Change spark plugs.

Try ko clean IACV, hope fully eto na yung sagot sa problem ko.

Check the air filter element, it may be clogged and the engine can't breathe normally. Clean or replace if necessary.

i have a civic 2004. encountered that problem already. they first cleaned the IACV and the problem dissapeared for a while, and after a few weeks it came back along with a CEL warning. they had to replace the IACV. After that it's all fine na.

I had it repaired sa honda. it wasnt cheap though.
