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.

POST 1 / ORIGINAL POSTEROriginal post

I have a 996 , I herited a k& n cold air filter on the vehicle. I'm experiencing a slight hesitation on cold start up.bit it clears after a minute or 30 secs any ideas guys its I have just given it a tune up new plugs and coils .it seems to run better since I solved the air leak at the mass airflow throtle body . but still not lnstant acceleration.is this normal .it has 54 k onit. .

Latency in throttle is definitely not normal with Porsches. They're known for instantaneous acceleration. Forget so-called "cold air intakes" on these cars. Find yourself a used stock airbox. If you want more performance, then buy yourself a 997.1 airbox. You need to get yourself a Durametric so that you can run more diagnostics on the car. This makes me wonder if you're not experiencing issues with fuel pressure/delivery.

POST 3 / ORIGINAL POSTEROriginal post

it was running quite rich . but since fixing air leak mpg has improved .vastly. now showing 22 mpg on highway.

what is Durametric .?

POST 6 / ORIGINAL POSTEROriginal post

Quotes source post: 16989971

does my 996 have automatic choke . could it be sticking . and will an air mass cleaner do the trick. to help lubricate.

POST 7Original post

Quotes source post: 16990727

it has an idle air control valve. Its mounted on the throttle body. There is a tiny hole that allows air to bypass the butterfly valve in the tb and helps control idle. It may have to be removed from the tb to clean the passage. Not sure if u can clean and lube the sensor itself. Maf cleaner is not a lubricant.

POST 8 / ORIGINAL POSTEROriginal post

bought some mass air flow cleaner tooke the air filter off and sprayed inside will know if it was a succes tomorrow morning . these porsche air filters are bloody sensitive. fuel and air mixture has to be spot on . such a highly tuned racing engine. not ur run of the mill Honda civic. lol 😆

POST 9Original post

Thats not really gonna do anything. U need the remove the maf and clean it, but what u should do is buy an obd11 reader do u can monitor the maf voltage and see if its in the correct range.
