2009 3.6r (gen5) misfire after oil and filter replacement.

[imtl]

I had my 3.6r serviced yesterday; the oil and filter were changed, and the air filter was replaced (without consent, of course). All was good on the pickup and for the rest of the day, but I went to head to the shops tonight before they closed and violent shaking and misfiring appearon startup. Thoughts? Engine light, "S" Mode, and cruise control lights all flashing. I don't feel like I can drive it back safely to the mechanic as it's a little bit of a trip, but should I let them know? There is a tiny oil leak coming from either the rocker cover gasket or spark plug tube seal on the driver-side bank, it drips like once every few days. Is it possible oil is getting into the plugs, causing the misfire? It's not something I really want to check myself as it is a more intense job than a non-flat 6/4cyl, but I will because I can't really afford to get it checked/fixed/towed currently, given I just spent money getting it serviced

Do you have any ideas of where I should look, specifically, or is it likely just a tube seal leak or coil pack issue? I will first check that the MAF sensor and air filter/intake are assembled correctly in the morning. Cheers.

Spark plug seal is a possibility for the cause of your misfires, you can use an obdii interface or display your codes on the odometer using the light switch. Jammed open avcs oil control solenoid is another possible.

Did you figure this out?
