not the cooling...here is a list of wonderful things I have tried:
Brand new from the dealer IACV
brand new pcv
brand new dizzy
all vacuum hoses checked, rechecked, and checked again.
All coolant lines blead with temp control on full heat blasting to even get the bubbles out of the heater hoses.
not throwing any codes....so basically I just live with it...give the car a lil time when she starts up for the first time in the day and thats that.
