Please help with my CEL
 

Can someone please help me with these codes
CEL has come on my car, and these are the codes I got.

The symptoms are rough idling.
P1128
P1130

Thanks for the help.

You're going to have to get it to a dealership or a Porsche repair shop that has a PST2 tool... it may be an oxygen sensor or a mass air fuel sensor going out.

How's your fuel economy? If the box is sucking down the fuel faster than normal, it may well be a sensor. Get it looked at asap.

Both of those codes are from your O2 sensors on your exhaust. The front two right off of the first set of CATs and near the headers. I had the same problem for a little while, but I have a VERY modified exhaust. if you are still on your stock exhaust system then I would suggest replacing both of those O2 sensors and have the codes cleared from memory and you should be ok.

doesn't he need to replace all four? That's what I was told by my mechanic.

Not in my experience. I only had to replace the two fronts since I beleive 1128 is the one on the left and 1130 is the one on the right. After I replaced the front two(very easy to replace yourself when lifted a good foot or two, cheaper too) and cleared the stored and pending codes they have not returned in my case.

First I love the look of the car. Iwill try that when I get home in two weeks after Ireturn from a bussiness trip. Then I will post pics of my car. You will like. One more question I have the fabspped muffler but am looking for headers what do you suggest?

Does anyone know the part # for the front two o2 sensors?
 

This will be for a 2000 Boxster S. Thanks
