Replace 20% of the oil ~ one quart. Do not rev engine or drive hard. Marvel is oil so it's not like a solvent engine cleaner.
You can do some testing. Use an ohmmeter to verify that the coil is good. If it's bad you can just replace the coil. VCT connector is on top of the valve cover at front of engine. You could even jump power to the solenoid to see if idle suffers - but consult a wiring diagram.
