Another Idle Problem

[bigdaddy]

hi guys, i had the classic ISV fault, took it off and gave it a clean, no change, so I took the

Seems to be the season for this problem. Did you check for a good 12v feed to the ISV?

[bigdaddy]

No, so I ran out and done it, yes 12.1v

Does anybody happen to have a photo of where this location is because I can't find it for the life of me. Even a diagram if a photo isn't available.

Well its not the throttle body, took off, cleaned it, put back on, no change, but I did find no voltage at the cam sensor, could this cause bad idle Edited March 24, 2007 by bigdaddy

When I had the Cam Position Sensor fail on a Vectra it put the Orange Engine fault light on, I take it yours is not on? I think maybe you need some diagnostics as your next step, a lot of back street garages now have this equipment, or possibly a fuel injection specialist may be of more help to you. I

As far as I am aware, the mk1 gal does not have an engine light, never seen it light up with ign on,,,,,
