Finally got a hold of a OBDII reader that can gives the snapshot at the time of the CEL.

My two codes are 1133 and 1126 and here is the info I got from the reader:

RPM: 2804
LV (I abbreviated so can't remember what it meant lol): 29.4%
Coolant Temp: 204deg
LTFT 1: 28.1%
LTFT 2: 28.9%
LTFT 3: -100.6%
LTFT 4: -100.6%
STFT 1: 2.9%
STFT 2: 7%
STFT 3: -100.6%
STFT 4: -100.6%
Speed: 69mph
Fuel System 1: Closed
Fuel System 2: Closed

That's all I could get off the reader. Need a more experienced eye to tell me what it might be.

I DO have an exhaust leak that makes a pretty noticeable "ticking" sound when running, but wondering if the data indicates another area of problems.

Thanks in advance!

ps. This was done using an Actron CP9175 reader (http://www.sjdiscounttools.com/actcp9175.html). I noticed it has a 9 pin connector on the top which, from my research, says it's for Internet updates. Does anyone know if this will also allow me to "download" the data off the reader to the computer??
