okay here goes the full story.
my car is imported from Japan(euro version boxster s).
when it gets imported to my country(s. korea), they have to go through the very stricted emission test. more like sound decible test. i don't know what they did, some say, they stick a socks or weld more than 1 muffler to pass that emission test. this CEL happens right after the emission test.
and here, we don't have a reputable porsche dealer. (we have one porsche dealer, not many porsches either) so i am trying to get help from here.
i tried to put really high octane(premium +) gas at first. well this didn't help.
went to a shop who has scanner, but no code was found altho the CEL comes on and off. i lose very little power when the CEL comes on. not that noticeble.
even doing more than 120mph, the car seems okay and pulls hard(maybe very very little drop on power)
in normal driving, CEL doesn't come on, but when i push it hard in highway, the CEL comes on right at 6000-6300rpm.
stop the engine and restart the engine, the CEL light goes off.
my thought:
post O2 sensor is going bad --> but it has to show on scanner.
fuel injectors are bad --> has to show on scanner and i would lose significant power.
MAF sensor is bad --> i don't lose power or going into limp mode.
???
if i ever want to visit authorized porsche dealer, i have to pay $2000 to register and it doesn't pay anything. i still have to pay for using scanner($70 at least).
this little thing is making me go crazy here...
please help~~~
oh yeah, my car is completely stock right now.
oh today, i scanned again,
cylinder 3.5.6 misfiring.
but this code goes away after day or two with normal driving.
man...

Why would you have to modify the exhaust to pass emissions? Exactly what was modified and how?
I'm thinking you aren't giving us the full story here. What other modifications have been done to this car? Do you have a cold air intake or K&N? Aftermarket exhaust or exhaust by-pass?
