Ok thanks bill ill drive it another week and take a data log. Now i know in the mornings which can get pretty dang cold there is a sligh rattle sound coming from near the cross pipe which dissapears after it warms up . It started rattleing after the dealership fixed my oil o-ring cooler which requires removing the cross pipe. Now I know they didn't put new gaskets or anything in. I am waiting on all new ehaust system ie. downpipe header and up-pipe with grimm speed gaskets. But i have noticed a new problem leaking valve cover gasket! but ill post again next week thanks!!
