2000 Pontiac Grand Am GT 3.4L Misfire, MIL Lamp on
This car was towed in with water in oil. Replaced intake gaskets and flushed [...] problem is fixed. Now, when started cold, engine misfires on #3 and #4 for about 30 seconds. Sets code every time. Cant find any vacum leaks. Plug wires are new as are the plugs...
