Mackpro Posted May 14, 2010 Share Posted May 14, 2010 Found bad oil pressure sending unit.Oil is better than finding antifreeze in harness/ECM connection. We usually find antifreeze at the engine ECU and it can eat the terminal/pins out. Clean out the connections with electronic contact cleaner and recheck and clean every week for a month till it no longer showes up at the connection. Glad you found it.
