i went and asked mechanic and he said it may take days for sensors to dry out. so im going to let car sit but just now i went to bakc it out of drive way to park iinto a spot so i can get other cars out. im backing out and i feel a little shaking and i got the high idle which not as high as it was before but then i go to pulll it into spot i hear it droping in idle and a little shaky. with the high temps i experienced i could either have a cracked head or a blown head gasket. wcould i have one of these problems with the shacking?
