Hey guys,

I'm taking my brothers Integra R out of storage, and I've noticed a weird idling problem. It's been in storage for just over 4 months. The battery had been taken out and trickle charged all this time, with the wheels all jacked up.

I've put the battery back in, and obviously brought the car back down - went to start it, and everything started fine.. but after about 2 minutes the car started to "breathe".. basically reving up to 2.5k and dropping back to 1k while in idle. It drives fine, gear changes and all power options work, but when the car is coming to a stop or gets slow enough, the "breathing" starts again.

I'm a complete noob.. What's wrong here? It was fine when it went into storage, so I don't understand what could've changed??

 

Theres a little valve under neath the throttle body. If the car sits for mroe then 2 weeks the valve usually get sticky and causes the car to do that. Its called the idle air control valve.

 

I believe he is referring to the idle air control valve. Just so you know if you decide to take it somewhere.

 

Ah.. Thanks.. Doesn't sound like this'll do any damage..(??) Can it be easily fixed myself? If it can, I think i'll need a little hand holding..

 

What about gas? Did you put fresh gas in it. Add some seafoam into the gas tank to help stabalize it and put some fresh gas in it after storing it.

Those idle air control valves cause a lot of problems for people. I hate them sometimes

 

... a bit of a problem there lol ... no seafoam (looks like a all-in-one miracle in a bottle!) in Australia. So a fresh tank of petrol eh?

 

also when you start it up you want to make sure you dont push on the accelerator for about 5 minutes cause the ecu has to do a idle learn procedure cause of the battery being disconnected.

 

If you're handy you can remove the IAC valve yourself and clean it out by spraying it with carb cleaner.

This diagram shows the IAC as part 1:

 

Hey guys,

That seems to have done the trick (culmination)
New 100RON fuel and allowing the ECU to "remember" how to idle properly at first didn't make much difference... Changed the oil then took it for a spin around the block for about an hour.. idling steadily around 2000rpm.. left it, then took it out for a night prowl and jumping onto the freeway for some higher speeds

It's purring nicely now!

Thanks guys!

Still a shame there isn't any seafoam around down here... hmmm.. market potential?

 

Diagram? (still want to know where this problematic IAC is, and how to clean it - might as well)
