Replaced intake manifold on 2000 Mustang 4.6L GT with a PI manifold. Placed all wiring and lines back correctly and tried to start it but failed. It started briefly with starting fluid but after a while it didn't start at all; rough misfires. I saw antifreeze in the # 5 and #8 plug. I haven't cleaned it yet i.E. Dried them out. The car has been parked for months and the gas hasn't been replaced even longer. What do you think the problem(s) are? Is it gas? I had an additive, Marvel Mystery Oil in the gas. The car started before but with starter but it misfired due to a crack in the thermostat housing which leaked antifreeze into those plugs I mentioned earlier. Any assistance would be greatly appreciated.
