Check Engine Light when idling in park?
OK, guys. I'm a pizza delivery dork. LOL Anyhow, I noticed while on deliveries, I'll park the car but leave it running and run up to the door. I get back and the check engine light's on. But if I drive away, the light goes off about 15 seconds later, and will sometimes go on and off while in park (I noticed this last night while sitting in a parking lot with a lovely lady 
)
Now my dad thinks it's the new O2 sensor I installed. He said it might not be tight enough. I think it's the front main seal having a tiny leak and oil pressure drops while it's not revving high.
What do you guys think?
