About 1month ago my car started to rev around to 4k and drive it's self when in gear! i fixed this by replaceing the throttal possitioin sensor!

however driving around yesterday. ive had this flashing key light on for couple months now. it all of a sudden went out and car drove better than it EVER has!. Anyway stoped car and went to get xmas gifts! came back to car started it.... REV REV REV 4k idel...


fort ok sensor probs lose. open bonnet. sensor is fine and so is the connection. ok wierd... so i take it for a drive... and it drvies it self again.

anyway aftering checking all sensors and connections today i can't see anyreal problem and why it should be doing this!?

Could it be the Carb needs cleaning? Stepper motor? Auto choke?

anyhelp will be rewarded with rep! thanks guys

could be engine coolant sensor. i know you checked it but it could be worth changing it. £10

can i just ask, when you had to replace the throttle position sensor how much was a new sensor? think i may need one for mine.
