Idle fault
The fault goes like this :
When in Drive with foot on the brake the car idles perfectly. Push the transmission into Neutral or Park position the engine idle swings between too high and too low. Also most of the time the check engine light comes on. All suggestions are welcome. Video posted here : http://www.youtube.com/watch?v=XuAjfoj6Xok |

Re: Idle fault
This seems to be a common problem with SVXi lately, my issue didn't go away yet and I am pretty sure it is caused by ICV.
I assume I only need to remove the throttle body to reach the ICV? If so, how shall we clean it? I've heard it is a very sensitive part to clean, a strong solvent will risk damaging it on the inside.

SOLVED: Idle fault
As I suspected, removed the ICV today and had it cleaned with Carb Cleaner then Electronic Contact Cleaner, and put it back together. Car is AS NEW again. The idle stabilized as it should and I am extremely happy now.

Re: Idle fault [solved]
Finally got around to taking my car to Hamish to sort out the three check engine codes and idle fault.
Idle fault is as described in original posting. CEL codes are : 11 crank angle sensor 12 starter switch 37 oxygen sensor After three days of investigation he finally solved all problems in one step by disconnecting a relay fitted by an auto electrical at the same time as rebuilding the starter motor. Only been driven 30km so far. I'll get a 250km trip in on Tuesday. One of the CELs would pop up after travelling about 70km, so Tuesday will be the real test. During the diagnostics Hamish also cleaned the two crank sensors and removed an old alarm / immobiliser. These might have been contributing as well. Once I've proven everything is fault free, I'll take it to Bryan to get the remote starter & new alarm installed. |

My problem is mostly a high (sometimes very high - 2000 rpms or more) idle, and occasionally a bouncing idle when it's not high.
