Johnper Posted September 1, 2018 Report Share Posted September 1, 2018 Hey guys I have 2 electric fans on my 4G63 evo 8 ( 1 is spal for the engine cooling and 1 is for the AC) I start them both at 90°celcius through the G4. And the problem is that whenever they kick on the rpm drops to 500 and then back to normal. There is no problem with the iac, battery, or alternator. Any ideas????
