  1. I still keep working this problem, will be check the leak potentials this weekend, but I have noticed one thing- We are having real cold weather and idle is fine until the water temp get to full running state (180). At temps below the full operating temp Idle is fine, sits around 600-700 after it gets hot it sits at 900 - 1000 and when sitting at a stop light it will randomly jump into its lets Idle higher and start moving up to 1200 then continue to 1800. A quick blip and it goes back to 900-1000 My logical brain suggests a temp sensor making system think it needs to be richer and the syst
  2. No I had not checked the oil filler line, thanks I will track that one down. As soon as it gets a bit warmer I will start collecting values for those data points. Trick is I need to drag my laptop along with me to catch it when it is playing the idle game. Dan
  3. Loren & all, well 3 months later, new TB and seal, checked every place for intake leak. Cleaned MAF got better but still runs fine cold but after 30 min drive (my home trip) it gets back to the strange idle. You come to a light, it idles around 8 to 900 then will sneak up to 1800. Quick blip will bring it down only to start the event all overagain. I am not new to Porsche problems maintained my 944,968, built my track car and build motors. I have duramatic tool and can get hard numbers. But this one only when it is up to full running temp has me stumped. Could it be a temp sensor?
  4. Been getting my new (2 me) 996 C4 Conv up to snuff, but one lingering problem is an eratic idle. The car uses the electronic TB so there is no idle control valve to clean. I checked for vac leaks, cleaned MAF etc. It will be fine when cold, but after a bit when you come to a stop light the idle will fall to around 900, then all of the sudden will spin up to 1800 or more. A quick blip of the petal will bring it down for a bit then it starts to slip up. It will throw a 507 MIL code, etc. Sometimes I get a bank x lean MIL, replacing all the O2 sensors is an option but rather pricey maybe thi
  5. I also have the same problem, can I get a copy of the TS procedures? Thanks Dan
