my 01 boxster has similar is problem. whenever I set the cruise control on about 65mph and if the road is flat for about 5 minutes, CEL P0430 comes on. Never the other side.
car has 123K miles and did run into AOS failure 30K miles back (instant crop duster). maybe the O2 sensor was damaged.
I'm just resetting it and "thinking" about it.
no help but welcome to the party!!
