Throttle Body GUNK UP?

[Bigdawg2016]

I'm so disappointed in my Chevy sonic. I bought mine new in 2013 May, I have 88,900 miles so as can see lots of highway miles. It super cold last week here in Chicago, I got error code 84 on my dash, both check engine lights, car wouldn't rev and Traction control warning light. I drove the car 1/2 mile, got back home thinking I'm in trouble. Shut it off, restarted a few minutes later, all the lights went off except 1, but car was driveable. Since I had a recall, made an appoint for 3 work days later, earliest one they had. Weekend didn't drive th car at all. Monday morning same problem, same fix. Got to work, still very cold, but sun was shining. Start car up at nite, no errors at all. Next morning same error/fix, but it warmer, but now it intermittently totally dying. So I drive it to dealer, he is saying someone try to clean throttle body and it gunked up. Which is not true, only done oil changes, tire rotation, air filter changes. I had a turbo failure warning back in august. Same thing, turn car off, light goes out. Now dealer wants me to buy extended warranty plan. Anyone else heard this crap?

Vehicle message code 84 in my 2012 manual states: "Engine power reduced" aka limp-home mode. Usually triggered when the computer sees a condition it thinks is serious. You will need an OBDII scanner to see what specific trouble codes have been triggered.

As these cars age this should be standard maintenance every few oil changes: pull the intake manifold and look for the orange check valve (PCV valve).

Look very closely at fine print if considering an extended warranty, they tend to not cover much and usually a waste of money.

Better yet, seems like time to move on to a different make/model then. Really, pull the manifold? Come one... This Chicago you know how cold it is? People think I'm crazy for pulling the tires once a year and putting grease on the the wheel lugs and back plate so tires don't rust on to the car.

This sounds like a BOGUS point from the dealer. Would be nice to hear Chevy explanation, but I don't feel like pushing that boulder up a hill.
