2013 Sonic 1.4 RS issues.

[Ajmastro]

Hey Guys,
New to the forum and the sonic community.
3 months ago i purchased a new to me 2013 Sonic 1.4L RS manual with 107k on the ODO. This is my first turbo vehicle, so excuse me if I'm ignorant on regular turbo things.

Car has been running great, haven't had any REAL issues yet other than a few things I'd like clarification on if possible.

- The car idles smooth until it highers the RPMs a little and then it'll sputter and run rough while its idling high, and then smooth out and be normal once back to a normal RPM. The RPM according to the Tac isn't increasing a bunch, maybe 1-200. But I do hear what I believe to be the AC compressor kicking on not sure if that's what would cause it. Also when it does this I hear a slight squealing noise.

-the car once warm has a ticking sound its pretty noticeable. I've read this is common, although not sure if its the best for longevity or if there is something I can replace to quiet this down.. Its pretty loud, noticeable in the cab once the stereo is turned off.

only mods I've done to the car so far is
- ZZP Cold air intake
-ZZP coil pack
-Iridium spark plugs.

Mods yet to install
-ZZP ported manifold
-replacement PCV Valve/hose
-ZZP blow off valve
-ZZP Tune



Thanks for any help, much appreciated.
Jacob.

Welcome! I haven't been on this forum in forever and I'm sure there are others who may have better answers than I do.

I'm the original owner of my 2013 RS manual. It has done the ticking noise pretty much since day 1. I don't think there is much you can do about it. But I also don't think it will cause any serious problems. As far as the RPMs going up a bit when the AC compressor kicks on, that seems normal too. The AC pulls enough power for the computer to compensate and kick the RPMs up. 150k miles and I still love my RS. I hope you will get many happy miles from yours.
