Very High RPMs While Idling
Ok, so I put a new stereo in my car. I put 0 gauge from my alternator to my new battery terminal, and 0 gauge from my chassis to my battery terminal. I made a new wire go from the Fuse Relay to my new positive terminal. After all that the car started idling at high RPMs, and I changed the MAP sensor and the Throttle Position Sensor. Then I reset the computer, but nothing worked. Can anyone please help me fix this problem?
