Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Clean the sensor right before the intake that is attached to the air filter box.

Suggestion · Original poster
Should I try a spray cleaner into the throttle body to see if any buildup - but it looked very clean when I changed the air filter recently.

Use spray in heavy amounts like instructions say

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 2001 996 tip with 40k that has developed (or I just noticed) a slight idle issue. In gear stopped I can feel a slightly rhythmic pulsing but the rpm is very steady- it is the same in park as well. But if I just touch the gas to bring rpm up to @ 1000 it pulses up and down @ 200rpm each cycle. The car drives normally and it is not something that affects drivability but wondering what it is. New air filter, new fluids, well taken care of and no codes popping up. Top tier gas used, and no oil usage between changes at every 5k. Should I try a spray cleaner into the throttle body to see if any buildup - but it looked very clean when I changed the air filter recently. ICV possibly or an intake leak of some sort - what is the best way to test this? Thanks for any ideas to resolve this minor issure - before it might turn into something larger... .

POST 2Original post

I think the AOS(if on its way out) can cause some smooth idle issues, others will pipe in no doubt.

POST 3Original post

Can also be an O2 sensor getting ready to check out. The sensor will trip the cel when it does completely give up.

POST 4Original post

Clean the sensor right before the intake that is attached to the air filter box. Don't touch it. Just use the spray in heavy amounts like instructions say. Fastest first check to do.
