Throttle position sensor

Similar symptoms when the fuel pump goes bad. Just had that changed on my 2010 CC.

Did you fix the issue? I ran into the same thing and I'm trying to diagnose.

so here's how I fixed my "car" while I was replacing my ignition coils, my ignition coil connector was being selfish and not coming off, one seriously sore thumbnail, a little elbow grease, and BAM! it comes off...into 3 pieces. a little finagling later I can get the prongs on my coil to just touch enough to run properly for a while, I completely forgetting my connector was broken. so I replace my battery, start disconnecting it at night so I can sleep peacefully instead of worrying about it being dead in the morning before work and contemplating calling an uber just to give me a jump. still not remembering I taped up my coil "connector" in place. car dies on one of the biggest highways in the country from a broken fuse that didn't look broken at all when I pulled them, so I angrily shat out money for VW to tell me what my problem was. I get back to the other side of Florida and start having problems, dying while idling in park, stalling out while coming to a complete stop, going into limp mode, insane gas usage, you name the headache and i had it. decided to change my spark plugs because I just replaced some coils that probs didn't even need it. (I couldn’t afford the plugs when I changed the coils get off my back) so that solved the issue for a bit but this time I fucking remember my coil connector was completely useless and giving me issues. replaced the connector and everything seemed fine until it wasn't fine. it's never fine. why is a life constantly shitting on me? I’m not being a bitch, it’s not only a car problem, a car problem means 7 different problems that are way more important than a car. But require one, so back to the hemorrhoid at hand I have erratic idling, if I was to accelerate I would rapidly lose revolutions as soon as I released my pedal, like drop way too fast and in park it died, id shake a bit until i accelerated a bit more but would always end up in limp mode. Even after replacing my coil connector I still had a misfire and a crazy throttle. so I disconnect my battery, remove it from satans car, I connect both my leads together for about 10 minutes because let's be honest, it couldn't not help listening to a message board online teaching me how to reset the throttle body and do what ive never heard of before. Something called an "idle relearn". Now I reinstall satans power supply, put the key to "on" but don't ignite for a minute or two for my throttle body to get acquainted with the sparky juice box, started a little rough, drove it around the block ten times maybe 30 times(i swear people thought I was a murderer on the prowl), I went on a highway, circled the only part of hell I'm familiar with since moving here. and it never ran better, either it never ran better or it runs normal but it had been so long since I've felt normal that it feels like its brand new. thanks for coming to my TEDtalk.
