Sounds like the IAC (Idle Air Control) valve is bad. For testing purposes unplug it and start the engine. You should have a very low, but steady idle. If so, replace the IAC. Hope that helps! Jim

07 mercury Milan. Speedometer goes up and down while driving, pressing the gas it doesn’t really wanna go. Then it does but starts right back up.
