thanks for the reply but i do defiantly have a solid flywheel as i has it fitted when i had the clutch changed
Leading evidence: 'Install when i had the clutch changed' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check fuel trim' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I think you may be able to determine if you have a vaccuum leak by checking your fuel trim with a computer, but I'm not certain.

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.

hi all i had a lightened ( solid ) flywheel fitted to my 996 turbo last year and love the way it drives engine feels much more like what i would imagine a 911 engine to be like but ...
i do have a problem with the engine stalling seems every time i come to a set of traffic lights it just wants to stall does anyone actually run one in a daily ? as i would like to start using the car more often
i was thinking of getting the idle increased slightly but not sure if this would actually help :dont know:
any help would be appreciated
thanks
When I bought my 996 c2 I was told it had a lightweight flywheel and that this was why it was so easy to stall when parking etc. It turned out it was a vacuum leak that was causing it to stall so easily, and when I changed the clutch & flywheel, I found it was a normal dual mass one.
I think you may be able to determine if you have a vaccuum leak by checking your fuel trim with a computer, but I'm not certain. Hopefully Demort will be along soon and will be able to help you.
thanks for the reply but i do defiantly have a solid flywheel as i has it fitted when i had the clutch changed
in terms of vacuum leak may be worth a check as it does stall very easy and maybe the mechanic broke something when fitting the clutch :dont know:
Yep, I wasn't suggesting you don't have a LWFW, just that you might want to investigate the possibility of a vacuum leak. Are you getting all the boost that you should be? A vacuum leak becomes a boost leak under boost remember.
I had the tickover speed raised and a small hole drilled in the throttle butterfly. Depending on the tune it seems that the revs can fall so quickly that the idle speed control is too slow to react and can't catch it before it stalls. Once sorted mine was 100% stall free.

yes boosting very well around 0.8-0.9 boost might have to pay desgin 911 a visit as its one of there flywheels and just to see if they can confirm its acting as it should
The common one is as you approach the traffic lights you put it into neutral -
Car will then stall as the flywheel will not be heavy enough to keep the engine going - just in case this is how you are driving.
My car is looked after by Matt at Fearnsport. The other option is to keep your foot very slightly on the throttle as the revs drop, but that isn't anywhere near as easy.
