Codes and reader

Looking for recommendations for a good code reader without breaking the bank. Replaced all 4 O2 sensors and now getting both p0134 and p1115. Bought 2002 S about 8 months ago and have replaced or upgraded about 30 things. Its deflating to never drive more than a few miles without the CEL coming on. Any advice is greatly appreciated.

P0134 is for the 02 senor ahead of the cat on bank 1 having an interruption of signal;
P1115 says the heater on the same sensor is not working.

You have either a loose connection or a wiring issue.

I use an iCarsoft POR II with good results. Besides clearing the ordinary codes, it can also clear the 'service now' and airbag lights. I got mine on ebay for $130, I think. My local Porsche dealership started charging $35 to turn out the service light after doing it for free for many yrs. At $35 a pop on both of my cars, it doesn't take long for the iCar to pay for itself.

Thanks guys! I had a friend replace all of the O2 sensors but will recheck the pre cat bank one connection. The cheapo code reader I bought seems to work okay but Im hoping to get more specific Diagnostic information since its a constant issue. Car runs okay but it takes some of the fun away seeing the cel all the time. BTW- Do all Boxsters exhaust smell strong when starting up? Another friend has a 2001 S and has the same smell.
