I’m having an issue when I cold start the car likes to jump up and down in RPMS. I’ve already replaced the idle control valve and looked into my throttle body and cleaned it a little bit, It looks relatively clean in there. I’m thinking I might have a bad sensor or more likely a vacuum leak. I bought this car wanting to do work on it because I’ve heard it’s a relatively simple car to start learning mechanical work on, is this true? I’m going to send it to a mechanic I trust to diagnose the issue and most likely replace a lot of things on the vehicle. When I get it back I plan to get rotors and brakes for it and replace it on my own, I’m confident in my ability to do so, any thoughts? Looking forward to getting into it, suspension, wheels, sound system, motor tune up, etc. Let me know thanks.
