2012 1.4L idling rough
hello again everyone so i purchased this vehicle a month ago today for $1,950 at 196k mileage. i have repaired the coolant reservoir, all the coolant hoses and clamps, and the replaced the cabin filter. spark plugs, coil packs, cover gasket thing, brake pads & rotors, sway bar links, brake pedal sensor, flex fuel sensor, A/C compressor, recharged it, and just bought a battery that is yet to be installed (doing that today). after ALLLL of these fixes, it still idles extremely rough and high when turning on in the morning and just idles rough regardless. HOW CAN I FIX THIS??? it drives me insane, my whole car shakes when it turns on in the morning, and i can visibly see the RPM dropping and rising nonstop during idling. some helpful advice would be appreciated, i want to love this car, but its going to be hard.
