High Idle above 3k - Error Code 51

[dlfred]

Driving along today I had my car suddenly act as though the throttle was stuck partially open. I did not feel any extra play in the gas pedal but when I pshed in the clutch it rev'd above 3500 rpm.

Checked the error codes and all I am getting is 51. Anyone else run into this problem, before I start troubleshooting?

Don't know if it matters but recently on occasion when I start the car the check engine light, brake light and warning light for bulbs, come on. The three remain on until I shut off the car. Normally they are off when I restart, even if it is right away.


Thanks in advance.
