Idle after a long run...

[Mattdogg]

Hey guys,

I'm dropping some money on the V4 Wagon this weekend (radiator tank split open) so new rad and hose kit ordered and on the way!

However while I'm doing some work next weekend I thought I could try a couple things to address an idle issue that I have after a long trip e.g Rotovegas to Tauranga where when is off the gas and car goes to idle when stationary it cuts out and I need to restart the car. It doesn't really bother me to much, my go foot and peddle are like twin brothers, but for my wife it makes her abit nervous when she drives.

Some ideas to fix this would be great, and looking at a budget of about $250 available to spend.

Thinking about some things to try:

Aftermarket BOV (currently stock one)

Gaskets for Intake Manifold, throttle and idle and give all of this a cleanout? (Thinking of repainting manifold at the same time)

New leads and plugs (current ones I haven't touched so might just be nice to know these are new, wont fix idle)

Just trying to make the best decision really, just wondering if anyone minded adding suggestions for this. The car is pretty stock standard.

Cheers

P.S - I have this saved on my watchlist atm : http://www.trademe.co.nz/Browse/Listing.aspx?id=439754929

Thanks mate

Yeah that was what we were planning to do cleanout that and throttle body etc

Thanks for the reply

Quick question...

Still to do the idle control valve and throttle body (waiting on gaskets)

But since changing from the factory BOV to this HKS one boost has gone from 16PSI (on factory BOV) to 12PSI on HKS one. I am a real nub with this, I'm getting the readings off the boost gauge. Is this an issue I need to deal with before I cause some damage?

I know we installed a bung to block one of the hoses and connected everything else OK. Just want to check.

Let me know if pictures are required, and I appreciate any help and/or advice anyone can give me.

That is a fairly big drop mate

U sure the Hks is installed correctly and not leaking

It maybe running not right if there is a boost leak

Swap back to stock and see if the boost gets all right

Does it idle ok when cold ? Can u get it to idle when hot ? Might just be aicv adjustment

Yeah the idling is pretty rocky now from time to time (around town) where as before it would take a long trip and have the idle cut out.

I had someone else check the install of it and they said it looked pretty good, suggested that the BOV could be leaking but the gauge gets the reading off the line before it hits the BOV.

Someone else said that the Vaccum reading would be the giveaway, I don't remember what it was before, but the vaccum is -18 on idle if that's any help.

Cheers for the reply's guys, I might try putting the factory back on this weekend and see how it looks.
