I own a 2001 2.7L Boxster, but recently have been getting a check engine light (P1126 and P1133 and P0300). I am thinking possible MAF (cleaned today, but no change), O2 sensor or Vacuum leak some where. There is no rotten egg smell, so I would assume it is running lean. There is also no smoke coming from the tail pipe. I do all maintenance and repairs myself, but I like to figure out the source of the problem first.

Condition: Cold start....Misfire (solid check engine light) with engine bogging down with slight tip-in of gas pedal. When warm: Misfire is gone (solid check engine light), but engine is sluggish.

Has anyone experience this condition before?

Thanks,
Dennis
