Would be nice if you could monitor live data with the engine running. If you could I would look at the short term and long term fuel trim in Bank 1 & 2. Multiple misfires could be due to a vacuum leak. A vacuum leak will show up in the fuel trim numbers. The short term will be + because it is adding fuel to the engine and the Long term will be - because it will be lean due to the vacuum leak. Vacuum is always highest when the throttle body is close when the engine is at idle and lowest when the throttle is open.
