92 mercury sable 3.8
so the car just started this on the 4th. it not able to turn off, switch the key to off pull it out car keeps running, been pulling the battery cable, but was told I’d hurt my alternator if kept doing it that way. just trying to fix it, so I tired switching out the ignition cylinder. that didn’t fix it and also checked all my fuses they were all fine. my next idea is to change out the whole ignition switch instead of just the cylinder but i thought i would ask the forum if anyone had any ideas.
now the second problem that i was trying to nail down before the other started was a issue with the car stalling at idle. it only happens if the car is up to temperature and it’s a hot day. plus 75 fahrenheit. just trying to go with cheapest parts and work my way up i change the air and fuel filters. then this other issue started and took priority.
any help or ideas are greatly appreciated. thanks for your time.
