Hi All,

could it be one of the tubes clogged? or what??

It has been discussed extensively in the past (back read about P0400) and I for one struggled with this CEL. In the end there is a pipe to the right of the IAC port with a sensor on it. There are 2 bolts at the top and at the bottom. You must remove this pipe and remove the carbon that plugs it. The guys who worked on this CEL had been right all along. This fixed my problem too.

Read this thread and back read (http://forums.maxima.org/showthread.php?t=481325)

Good luck, stglock
