Hello ,, the p1000 code is not important at this time, that code just means that the computer has not run all the tests on all the systems yet.. when the check engine light starts to flash , this means you have a major misfire condition that will damage the ctalytic converter. Im suprissed that you did not have a misfire code!! from what im gathering , you may want to start with a complete tune up , plugs , wires , ect , and see if the misfire goes away, when under a load it must be running poorly, if the misfire goes away then chances are the code for po234 will go away also,, witch is a code for an overboost condition ,
was the problem ever resolved? and what was the fix
. Please post.
