The problem was lessened with AC off and the motor warm but it was still happening from time to time.

Since my car arrived in Australia after a few months of not being used during shipping from the UK I found it had developed a tendency to stall immediately after starting or when approaching a set of traffic lights.

So this past weekend I pulled out the Idle stabliser valve from the side of the throttle and began a clean up using a spraycan degreaser and cotton buds.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

I applied some wd40 before reinstalling it and sure enough the problem is fixed.

POST 1 / ORIGINAL POSTEROriginal post

I thought I might share  the solution to a problem I dealt with this past weekend. Since my car arrived in Australia after a few months of not being used during shipping from the UK I found it had developed a tendency to stall immediately after starting or when approaching a set of traffic lights. The problem was lessened with AC off and the motor warm but it was still happening from time to time. This had not been a problem last year when the car was in regular use. So this past weekend I pulled out the Idle stabliser valve from the side of the throttle and began a clean up using a spraycan degreaser and cotton buds. it wasnt long before I discovered that the spindle was actually spring loaded and when de-gunked it actually sprung back to an open (or closed) position when not driven by the motor. The point there is that when I first took it off the car the spindle was binding in a given position due to excess muck. Once it was degreased it began moving freely. I applied some wd40 before reinstalling it and sure enough the problem is fixed. This solution wont apply to later model cars that have E-throttle since they don't have an ISV, but the earlier cars with a cable throttle may benefit from an ISV clean if your having idle issues.

POST 2Original post

I have this problem with my 944S2 at the moment. I am waiting on some parts to arrive before diving under the inlet manifold. I grabbed a spare out of the future rally car, gave it a clean and test. Combined with new hoses, fingers crossed it sorts my idle out. Greg
