Ontopic The new car-seching thread

You haven't heard any of that? Its bad enough that the only person from the show to get a spin off was the white woman love interest.
I think she's the most interesting to look at and she has that nutty giddiness. The other actors are good and will hopefully get other work soon, but KC boxed them in a lot with their ethnicity. I do wish KC would have continued. Cute show, ethnic stereotyping notwithstanding.
 
Got invited on this "Dapper Drive" to help raise money for prostate and testicular cancer and the more nebulous bits of Movember charity. Any of you dicks want to donate, I'll appreciate it.

2009 Corolla starting pulsing and hunting below 2000 RPM this morning. Fine at higher RPMS.

Thinking first to replace all the spark plugs and check the ignition coils. Those are a weak point on the corolla, it loses an ignition coil about once every 2 years.

Normally it throws a code because its completely misfiring, but this isnt quite that bad, and theres no codes. Still not driveable though

Carpeople Thoughts?

Hunting is usually a symptom of unmetered air going where it shouldn't.

I would check out whatever vacuum lines you've got, and look for evap codes. If it's got a DBW throttlebody (I think it does), you might consider checking for smooth operation of the butterfly and cleaning it up if it's sticky.

If you really suspect a coil, disconnect them one at a time and see if you can find the one that doesn't affect the idle.

the more i read and watch the more im guessing its the throttle body. Gonna try to pop that out and give it a good clean before doing anyrhing else.

DBW is really annoying that way.

Hopefully since it's 2009, it's still port fuel injected, and the intake manifold isn't all carboned up.
 
Our Q5 has the same thing. Keeps the intake valves clean and avoids that whole "pull the intake and walnut shell blast everything" maintenance bullshit that pure DI engines require.

Lots of people with older TFSI motors add an oil catch can to the PCV system.
Yeah, that's going to happen in 2 years or 24000 miles on this one too. Catch cans are cheap insurance against bullshit buildup in the intake.

Depends on where the leak is, but either way it'll affect the idle somehow.

If it's on the vacuum side of the manifold, the idle will drop down. If it's on ported vacuum, it'll surge a bit.
Tore things down last night (surprisingly easy, love toyota and honda engine bays). Did all the plugs (they were due anyway), checked the ignition coils by unplugging one at a time, cleaned the throttle body.

No luck on any of those, but the hunting did quiet down a bit when i unplugged coil 4 (one i just replaced in june).

Throttle body:

^^ A little grubby, but nothing crusted up enough that it would keep it from closing or impede its movement imo.

Put it all back together (after snapping a plastic coolant nipple just by touching it..... fuck me that was a mess), problem is still there :(

sprayed carb cleaner on all the vacuum lines i could see, no change in idle.

But I did get it to throw a code after driving it aggressively, cylinder 4 misfire. I think that new ignition coil might be bad. Gonna swap it today.

If its not that, might an injector or something on that cylinder :(

Injector should ohm out at 12.

IDK how to test your ignition coils, but if you replace, do it with a reputable brand (on a Toyota, I'd look for a Denso unit). You wouldn't believe the amount of counterfeits on amazon for those things.
