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.

Today I filled up and as soon as leaving the station I get a check engine light. I get to work come to these forums and read... Thinking its the gas cap I have a friend read the codes. He reset them before I could write down the code. Left work and drove 20 mile no code
go to a fund raiser (save "the Tata's") breast cancer awareness. When leaving I start the car and the check engine light is on again. Head to autozone and get them to read the codes. P0030 AND P0134. It apears to be a faulty H02S11 (bank 1 Sensor 1) they print up a price list $66.99 universal fit and a 127.99 Exact fit.
Is this a DYI??? and what part should I look at getting???- 2002 996 coupe
Can't be sure without troubleshooting but it does sound like a bad bank1 pre-cat O2 sensor.
You can get a OEM Bosch from Amazon

To do troubleshooting, you need at least a generic OBDII scanner that can read O2 sensor voltage in real-time. To replace the sensor, you will need a special O2 sensor socket (prolly can be rented from auto parts store) and a good ratchet/breaker bar for leverage.

Note that if you wind up breaking the old oxygen sensor and you have to grind part of it out, do NOT do this near your oil drain pan...it can add a dimension of stress to an oil change that doesn't really need to be there.
