Hey guys! Replaced the check engine light and was able to pull codes. Giving me the code 21 (TPS). Car is an 1985 Cutlass with 307.
No other engine codes.
Also, found these cable plugs unplugged. where do they go? 😂
Thanks in advance for the help!

Last one dark green wire is for the AC compressor I believe.

2 and 3 are for the power antenna if I'm not mistaken, and the green one I also have and is not used, I can't remember whats its actually for at the moment. Electric choke option?

Thank you! Good to know it wasn’t anything important that was unplugged. There’s no radio in the car so the antenna is the last of my worries.
So now I’m thinking I’m going to have to get replace the TPS....unless there’s other things I should check first that wouldn’t involved taking the carb apart?
Car runs with a slight lack of power (not that it’s a hot rod or anything), decent idle (cold and after warm up), has a light exhaust leak coming from driver side area of motor, shifts smooth...
If it came down to it, I’m not familiar with replacing the TPS, but any tips help.
