oil pressure trouble
 

:mad:I own a 2006 impala ss with the 8 cylinder dispalcement on demand engin when i park my car overnight or for a long time and then start the car the oil presure guage regesters at the bottom and it takes quite some time for the pressure to come back up to the normal midway point on the guage.

the other problem i have is the temp sensor only working when it is cold outside when the temp climbs up between 50 and 60 degrees the temp only come as dashes
