Question about 2000 Lincoln LS
Does anybody know what this code means and a possible fix the check engine light is on and is has a rough idle and misses between 40 and 50 mph otherwise runs fine. from everything i read it sounds like a bad coil but this was the code i got when i scaned it. thanks
P1633 means KAM (Keep Alive Memory ) Voltage too low. the KAM is caused by low battery voltage and you replace the battery.When you replace the battery the KAM loses Memory and the problems resulting in what you are experiencing now.When replacing a new battery, reconnect the Positive cable first.And use a trickle battery charger set low to the cables before disconnectng the battery . this will keep the voltage to the ECM powered with enough voltage. All you can do now is make the computer relearn the way it should run. Disconnect the negative cable from the battery, wait a while 20 seconds or so. then reconnect the cable. I do not know if this is a temporary fix or not but it should re-program the computer.

you probably have a vacuum leak. check all your hoses pcv hose for sure. it means the engine is seeing too much air with the fuel.

SOURCE: which ignition coil is bad?
I went thru this on my 2002 LS as well.
I replaced one ignition coil at the dealer - only to get the same misfire code on another cylinder. After a little research found out is actuall a gasket/o-ring problem design of the block. Spark plugs are deep in the block - under the oil - which is why they are supposed to last 100,000 miles. But the o-rings start to leak some where between 65k-85k miles. Coils go bad because of oil contamination. If you don't solve leaking oil problem will have to replace coils again - but sooner - because leaking oil will be progressively worse.
Cost - 8 ignition coils
set of spark plugs (who knew they were that expensive
and a ton of cash for the labor to tear down the top of the motor

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.
