2013 Corolla S new intake, leaky tailpipe, weird RPM

[ch1ckf1x]

So I've got a 2013 Corolla S, 1.8L, and I just got back from running errands.

Noticed something weird, that is, my tailpipe's leaking a bit of water.

The kicker is, I just slapped on a RAM air intake today. Could that even be related, or am I tripping?

On top of that, one of my fan belt pulleys is super squeaky, and the car feels like it's 'hunting'.You know, like the RPMs will barely jump up for about 5 seconds, then settle back down. It's just a tiny spike, but it's noticeable.

Anyone got any ideas what's going on, or if the intake messed something up? This little Corolla is acting wonky

Its just condensation dear, especially if it's cool out, and the RAM intake probably isn't the issue, I'm guessing map sensor or vacuum leak, check the intake connections and that squeaky pulley too

The water from the tailpipe is normal, just condensation, especially if it's your first drive after sitting or a short trip, check all the connections on the intake and maybe clean the MAF, squeaky pulley might just be coincidence

I'm thinking 4 different issues that aren't related to eachoter. For the water in the tailpipe, before I say it's normal I have to ask how much? It's summer, so there shouldn't be as much as in winter. The intake has nothing to do with the water, but may have something to do with the rpms, which I honestly doubt. That could be from idle control valve, the throttle body, vacuum leak etc. Your problemem with the pulley is in the pulley, probably a bearing gone bad, so jsut replace it

I experienced something like that when I put an intake on my old Corolla. The RPMs were all over the place, and I got this high-pitched chirping noise from the front. Turns out, one of the belt-driven components had a worn bearing, and the intake clamp wasn't tightened properly. After I fixed that and replaced the noisy part, everything's been running smoothly. It could just be a combination of little issues adding up for you, too.
