Hi new to ls1s Pontiac gto here questions Help Hi 2004 Pontiac GTO here. Moded. Long tube headers cam tune CF Clutch. It used to run very cold all the time so i figured the therm was stuck open. Now i changed it to its OE therm, now the gas miliage went down and the fans are on full blast when the temp passes its old temp n they never turn off? Help???
