Idle issue?

However if your vehicle stalls, our you get a check engine light immediately contact your dealer.

For example, I've noted 4 missfires after near stalls, but I'm not taking my car in citing vvt our cam valves. Too many people crying wolf can do more harm than good.

Yeah, I hope that people don't start panicking yet. Hell, this cam issue could be limited to a small run of 5-10 cars while some assembly worker was dozing or something even more asinine...

Or one faulty valve that threw off the other when it failed.

It's really just a guessing game from here as well. I'm curious to know if I save the same problem as Whiteout-frs, and I'm itching to find out this weekend.

I get another drive with my friend's FR-S AT. If I put the car in Neutral, rev the engine up and let it settle, rpm can go to 500 ~ 600. I tried a couple of times, it always does that. But I don't feel particular engine vibration as if it is about to die. If I pull to D from 600 rpm, with brake pressed, the rev drops to about 400 as the engine takes the load and quickly goes up to about 600 ~ 700.

BTW, the fuel is about 50/50 mix of dealer fuel and shell 92.

Other members on a separate thread are reporting factory oil levels that are significantly overfilled (per their measurement). Anyone having idle/rpm issues should check their oil level. Id be surprised if there is a correlation but stranger things have happened. Also I was wondering if the oil is way overfilled if that could somehow affect the cam timing mechanism?

Overfilled oil shouldn't cause the weird idle... well, I haven't heard bout it.

Aren't the oil levels checked during PDI, so wouldn't they catch it then?

lol PDI.


Mine seems overfilled as well. I just assumed they wouldn't f that up from the factory.

BUT I do agree w other stuff. Don't need to freak out if you never had idle issue or never stalled on you.

IDK, I didn't think the new Impreza 2L was very smooth when I had it for a loaner briefly. And my 07 STI had "hiccups" at idle.

Fuji Heavy Industries apparently doesn't care about overfilling, little moisture and panel fitment..

Could overfilled oil cause issues with cam timing since it controlled with oil pressure? sorry to get off topic.

2L? Oh FB20 engine Impreza? Huh, I haven't driven one, so I can't answer that one. I've driven on EJ series ones (both NA & turbo)

As for STI or WRX is different story. GOD, those things get so much hiccups. I've never driven any STI or WRX that didn't have hiccups. As for my Impreza (RS), I have never have hiccups. Of course, it has a lot of mods to make it hiccup free, but when I'm at the stop light, my RPM never moves.

Hm... overfilled oil for boxer main problem is sucking into intake and will have fun w full white smoke LOL

Maybe it is overfilled oil... maybe not. We'll wait & see other member's report on the cause of this idle problem

My Brz kinda reminds me of how my STi idled. It feels like it almost misses every once in a while, but it definitely isnt shaking violently and about to stall. I havent been worried about it so far.

Because the people at the dealer who do PDI don't give a shit. They dont check half the stuff they are supposed to.
