Hello, I'm newbie here... ( My00 boxster 2.7 manual transmission)

I live in Seoul, Korea and I don'n speak English, Sorry...

I've got some problem, today cold morning I turn on the car and it's nomal condition, after few minutes flushing CEL light

I have a OBD2 reader and read that code P1219, P1577, P1578

I drive the car few mile, at low rpm(0 ~ 3500 ?) is good condition, but over 3500rpm is so bad.. It's like a bad MAF sensor

After replacing the MAF sensor the CEL comes back again...

bad DME? or bad fuel pump?......

Please help me.... T.T

My '02 Boxster S just came up with the same set of symptoms. Did you ever figure out what the fix was?

 

See my post #2 above - it pretty much has to be the pedal sensor. Or a loose connection at the pedal sensor.
