Message	Oem orings pressure tested them in the 300 degree fuel rail to 65 lbs under water with no bubbles before installing them . What else could cause a leak on only that cylinder ? Could a lower plenum gasket leaking on #3 cause that ? My vacuum at idle is 18 , not so good , almost like I have a vacuum leak . But my AFR on both banks is soild at 13.0 at idle . Wouldnt my AFR on the pass side run leaner ?
