When changing the spark plugs we didn't realize how stuck they were and broke the head of one in the ratchet socket. What would be the best option to get the threading out of the engine? We're thinking of taking off the head to see if we can get to the plug from underneath.

My check engine light isn't on but on the message board it says service engine soon. What does that mean? It's a 1994 seville

Soon what does that mean

sometimes the message comes on, some days not. Replaced oil pressure switch at dealer and the message and sound was constant so they reinstalled my old part and I am back to the sporadic message and sound. It must be a false read. Dealer said oil pressure was at 12 psi at idle and increases with rpm it should be at 5 psi at idle. Now they say it might be a faulty ipc (instrument panel control). How can this be fixed or can the warning sound be disconnected, the message I can live with but the warning sound is irritating. Before the dealer experience, another shop said oil pressure was good and replaced the current oil switch. So the switch that I have is actually a replacement from the OEM part.

I crank my car an let it idle after 3 or 4 min it say engine hot an shut off
