You need to verify that oil pressure is ok.
They sell gauge at the parts store which has to be connected to the engine block via oil pressure sender hole.
For that , take out oil pressure sender(unscrew) and screw the gauge in to the hole (con thread).Run the engine and see if pressure is ok at idle and on higher RPM.Gauge suppose to have scale (norm. , low , high ).If oil pressure within specs , repl. oil pressure sender.
Or just replace oil pressure sender and see if that helps.They are not expensive ~ $30.00 , gauge probably the same money.

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. The number of codes that can turn the light on number in the hundreds. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.

oil is non conductive so I doubt that's the problem, but the oil leak should be fixed to reduce problems down the road.
as for the misfire could be a couple things, fouled plug(s), a plug wire(s) that has cracks, or even valves that are not seating which i doubt from your explanation.
I would change your plugs and wires first, and fix oil leak. if this does not fix the issue there are other things going on.

You need a code scanner hooked up to it to find out why the light is on.
If there is an advanced auto or an autozone near you, go there and tell them the engine light is on, and you need a code retrieved. They don't charge for this, where other places do. Tales about a minute.

If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything from a loose/faulty gas cap to a transmission issue.
This
light comes on when the computer detects a
fault of some sort in its diagnostic tests. If it keeps detecting this
issue, the light will remain on. If the light turns off, then it has
detected that the issue may no longer be present.
In
order to find out what the exact reason was for your light, You need to
have your car computer scanned to retrieve the code that
the computer would have stored when the light triggered. Most garages
will do this free of charge. The code will tell you what may have
caused the light to initially turn on.

get somebody with a scanner to check the codes
