3.2 egas doesn't have a ICV either, I found a post by P51-Mustang on renntech that shows the MAF (which has been changed recently) could be the problem, going to play around this week and see if I have any improvement. I had these same CEL codes P1128 and P1130 while driving home from Missouri to Maryland a few months ago. Porsche stated could have been triggered by driving the car 1000+ miles in a short period of time. Since I got home and after 1,500+ miles, CEL has not returned (fingers crossed)

Great write-up on the how-to. I have been meaning to do this for the last year or so and finally got around to it today. Only took a little over a half hour for me to do the job and get the car back together, and boy, was that sucker dirty.

I was suprised because I regularly use injector cleaner in my fuel. There was a pretty thick buildup of material in the throttle body, especially on the lower side. Rags and carb cleaner did the trick to make it look like new. When I started the car after the cleaning, I noticed the idle was smoother right away.

I have 75K on my 2000 base boxster and based on what it was like getting the bolts off, I suspect this was the first time the throttle body was cleaned. Based on how dirty it was, one would think that cleaning the throttle body would be part of the regular 60K or 75k maintenance schedule for our cars....
