Thanks Loren, I saw those. I needed to buy a replacement air deflector as it is missing on mine. I ordered a used one, and then saw your post so I wanted to see which ones I got. But maybe I missed it in those TSBs, I don't see a change to defector, I guess it maybe consolidated as part of new frame.

thanks again for pointing out those TSBs!

Hi Loren, I searched through the 996 TSBs but did not find one pertaining to a new style deflector. Can you help? Thanks!

Have a look at the TSBs on the sunroof.

There is one for a new style deflector and another for various noises.

Thanks Loren, I will need to look into this VarioCam test...

I wanted to update all that after driving 3500 continuous miles over the course of 9 days I didn't experience any CEL. It seems like that was fluke, but I will plug in my OBDII reader to see if any pending codes have been captured later this week and keep monitoring it.

Thanks those that replied with useful information.

Happy New Year!

Loren, I posted fault codes in original post. Are there other codes I need for further diagnostic? maybe from Durametric tool? thx!

oh weird, I thought I posted a reply to goldenwarrior thanking him for the link prior to my trip.. that linked helped a bunch and really gave me some confidence that maybe o2 sensor was the culprit and not something bigger.. this was very helpful especially before a long road trip..

thanks to all for the definition of pending code, i googled it after posting here and found that info too.. i never knew about pending codes for as long as i had my scantool, then again i haven't used it in 5 years or so..

Glad to update that after 1k miles in (13 straight hours yesterday to bay area, then 6 straight hours today to Irvine), the issue hasn't occurred again. As a matter of fact, car is running in top shape, with long stretches of 100+ along I-5 in mid of Cali.. Man the ROW M030 rides amazing over all types of bumps and undulation.. (side note, after living in WA the last three years, i realized how much i miss cali driving!!)

Will keep monitoring CEL and update this thread when necessary.

Hope you all had a great Christmas!

This morning, I went to top off .5 qt of oil (knew I was a little low from an oil-change a week ago). Started it up drove it out of garage onto driveway, and let it idle to warm while I run in the house to wash hands etc. Then came out and noticed the exhausted sounded weird (like misfiring), and noticed CEL was solid lite. Shut her down, check the oil cap and retighten, and restarted it, CEL still solid lite, but the car idled fine, and no misfire was felt. So I drove it into the office since I realized my Scantool is in the office...

So hooked it up and captured the following 4 codes

P0300 (misfire)

P0301, P0302, P0303

& 5 [pending] codes, not quite sure what pending means from scantool:

P0130

P1313

P1314

P1315

P1319

All looks to be from the driver side bank.. What would cause misfire to single bank when cold? Could topping off oil caused this? I was pretty sure the oil cap was tight first time around. I'm very sure Oil is clean, no intermix problems (checked coolant color the other day after changing oil, and dipstick still clean).

Car is a 99' 996 that I picked up 1.5 months ago and passed PPI from Squire Automotive. No CEL since purchase, nor any codes during PPI.

About to take car for a 3k mile trip to San Diego tomorrow.. I will bring my scan tool and keep monitoring it.. So far after clearing code, car runs good and CEL stayed off.

HAHA! Your subject had me there for a sec.. Glad it's a positive thread.. Just bought mine a month back at 88k miles, so I look forward to hitting 100k soon!! Beautiful car! Glad you keeping her.
