74 Cylinder 4 Misfire Detected


AP1, 120k miles.
I add 1 qt oil in my engine yesterday and drove 10 mile (1 drive cycle)
dip stick reads 5x at 3 bars engine temp
Then, after I starter the car again for 10 second, got the CEL,

Also got

ABS
12

EPS
23 A problem with the circuit for engine speed signal

These 2 seems not related as I just did something on the front brake, the grease may affect the circuit.


My car burn quite a lot oil, 1.0~1.2 qt per 1000miles.
Can I still drive the car without damage anything?
Will adding the oil cause the problem?
What should I check for the problem?

 

car also idle rough 2,3days before the CEL
jumping around from 700~800rpm


spark plug changed 20k ago.
will it be the problem of the seal?

 

help!

 

i found some fresh oil on thread of the spark plug 1.
oil getting in the engine??
