Can you post a photo of the piece that fell off?
I turned a corner, was in 2nd gear, didn't downshift to 1st (like an idiot) and car stalled, bounced a few times. (usually the stalling procedure)
A little rubber lid of some sort fell off, 4-5 inches in length, 3-4 in width. Hollow in middle so as to slide onto something (had a little black fluid inside, not much just enough to get my hands dirty).
After stalling, I tried to start the car. I would turn the key to ignite and all I hear is ONE clicking sound. Then nothing. Not the battery, it's new. Not the alternator, jump start won't work.
Anybody have an idea what could be wrong?
