I really hope someone can help. i recently posted thread where i had some issues and fault codes http://www.astraownersclub.com/vb/sh...d.php?t=248844
I have now managed to clear 2 of them and am left with only one:
0505 - Idle Control System Malfunction
The problems im getting are when crusing the car wont stay at a steady speed. if i try to maintain 50 mph for example, the car feels like it loses power and the speed starts to drop. i put my foot down to compensate and there is a second delay and all of a sudden the car jolts forward with power and picks up speed but i cant keep it at one speed, and this process repeats. and im constantly putting my foot down, taking it off, putting my foot down, taking it off.
I know theres ways of cleaning the ICV, but mine is a sealed unit attached to the throttle body. if the ICV is faulty and needs replacing, would that mean il have to buy a complete unit including the throttle body?
car details are: 1.8 16v sport - 1999 v reg - i believe its an X series engine
Any thoughts or suggestions would be appreciated.
