Question about 1993 Lincoln Continental
The valve stems seals should not effect the engine running at all. At most some exhaust smoke. You will have to look carefully at the items you took off when you were working on the engine. If any wires were taken off or knocked off the distributor cap, they may have been put back on incorrectly. Also vacuum plays a very important role in the way your vehicle runs and of course climate control inside. Go over all the vacuum lines carefully , may sure they were not switched or that hidden connections were not missed( not plugged back in at all). The same thing goes for any wire harness plugs that were disconnected for access to the valve covers. One missed sensor wire could be the source of the problem. Use a small mirror if necessary but look over the entire engine compartment. You could even have a broken ground cable to the engine or alternator giving you head aches. Replace any broken ground cables you discover , This is important for proper operation.

If you replace the valve stem seals without removing the cylinder head as I understand, and let's say the seals where correctly installed. Two thins could have happened, some oil got into the burning chamber and got the spark plugs, fouling them, or the oil bot carbonized on the seating base of the valve or the sealing surface or the head preventing the valve from sealing properly.
Check and replace your Spark Plugs if they are fouled, Make sure all vacuum hoses are good and tightly connected.as well as all the electrical connectors.
Good luck and Keep me posted!!
