Damn man that is terrible! Just finished and then wrecked so quick! :(

As PCB as saying, and as my experience has shown, sometimes just inspecting the vacuum hoses is not enough. You may have a leak you can't see that causes this trouble. There are a lot of little hoses on there..

Lol!

Update: took it to the shop last week and they did a "smoke test" on it and somehow found a vacuum hose back there in the EGR system that was leaking! I thought I had inspected all the hoses, but damn, it seems you really need a better way than just a visual to find these problems. After all...

^What he said :) FYI, I just took my IACV off last weekend using a new #2 JIS screw driver and went 4/4 no stripping. They all were crazy tight and went *CRACK* when they busted loose, but no damage to the fittings on any of the screws.

I didn't do the carb cleaner test, but I did really give all the hoses a good inspection. I guess I will try that later if the shop can't figure it out. Just dropped it off this morning at a really good shop we know. Will report back if they find anything. Fingers crossed.

That just seems insane to me. I've owned a lot of different brand cars (American, Japanese, German), and never heard of a simple issue being simply unresolvable, to the point of just ditching the car. There has to be a solution. Mazda can't be that bad.

I saved the original IACV. I will clean it up and try swapping it back out with the aftermarket one and see if it works, assuming the shop can't find anything. I bought the nicest one on rock Auto for $180! The OEM one is like $400!. That's the only reason I had to try aftermarket.

Maybe, but i mean it doesn't seem to get better, even after driving for a week to and from work (20+ minutes each way with stop and go). It's like a hard drop and then recovery, not a oscillation.

Whoa.. That sounds like it would make some pretty bad noise though...

Haven't tried the Sea Foam yet but I did run a whole bottle of 3M fuel system cleaner in the tank. Since this is my wife's DD, I just had her take to a shop this morning. Will report back if they find anything. THis has been super frustrating though. I've never had a car with as touchy an idle...

The EGR tube comes off the side of the exhaust manifold and goes under the throttle body. If you have the throttle body off it's easy to see. Both ends have a 26mm nut on them which I would recommend spraying with PB blaster to loosen up. I was only able to crack the manifold side one free, but...

OK, ya'll. I'm starting to get to the end of the rope here on figuring out my idle dip problem. The car runs fine except when ideling it will dip randomly (say usually 1 or 2 times during a typical traffic light wait) down to 200RPM or so and pop right back up to 700. It dips so low that it...

I see em around here a fair amount, but we have a lot of older cars since we generally don't salt the roads. Thank goodness. Chicago...yeah you're lucky to find a car older than 5 years or so that's not rusted to the ground lol.

And sure you can drop it down just a little a bit. Most of the sport springs will tell you about how much drop you get.
