Yeah, sorry to revive this thread, but the original photos aren't working no more, does anyone have photos to confirm for this?


Thanks

cleaning the iacv is one helpful thing. my idle still plummets to 500 rpm when i depress the clutch. seems to be intermittent. my iacv didnt have a gasket. i have seen people selling a gasket for it but i doubt if it needs ones. but not sure. wish there was a complete explanation of the idle system. tried to buy a new iacv but they sent me one with different plugs to mine. so the 1991 is different. amazing how little info is in these forums.

Well the reason I say that is, in one of the articles, it suggests that removing the IAC valve is "easy", on the S14, my s14 anyways, it's clearly not.

What I'd like to see is the instruction and photos, on how I can clean this thing without having to remove the IAC. I want to be able to confirm which hose I can spray into, to clean it.

Thanks for any help though.

That photo definitely helps, I know which hose now runs to it from the front.

This thing is between the firewall and the intake manifold. On my S14, it's a tight sqeeze because I'd also have the ABS to contend with.

Thanks for the photo once again.

Defective ECT means pinging/f*ed up timing and horrible a/f ratios.

I hate to bring this thread from dead, but also hate to make a new one and then get told to search when I already read this thread...but like said the pix aren't working. I no longer have stock intake, but an injen. So the hose you spray the cleaner in for the IACV...would that be the hose that runs off the bottom plastic T that the valve cover breather hose and the hose running to the intake go to? I see it leads all the way to something under the intake manifold, so I'm assuming thats the one I need to spray...thanks

yeah I personally took my iacv/acc valve off of my intake manifold and sprayed electronics cleaner in there instead of "automotive cleaners." it blew all of the dirt off of the contacts and everything in there and I purchased a new gasket for mine as well. I just need to test it out now to see how that worked.

No pix under the hood of my car, so I found a s14 on yahoo
You see the hoses near the intake manifold... there's 3 that are all connected by a plastic t...one short one u see running off the intake pipe and then one long hose going the the valve cover. The one I sprayed in is the third that is on the bottom part of the t, and runs to some metal pipe underneath the intake manifold.

I used throttlebody and intake cleaner...sprayed and kept the motor from dying by reving the car by hand. I used only half the can cause parents were complaining about the noise lol, but that much seems to have helped. Earlier today my car seemed like it wanted to die at the light and while driving..needle on tach would sorta jump and drop a line. I experienced none of that tonight while driving since I sprayed the cleaner.

So I'm assuming I used the right hose lol..def was a vac hose

Forgot about posting in this thread..did I spray the right hose as I stated above?

Thanks. Also would AICV only affect idle/stand still or can it affect driving as well? I know the word idle is part of its name, but just wondering

Thanks

It's the bigger of the two hoses. The one closer to the driver side.
