My parking garage hates my car

I feel for you. Dang busybodies with nothing better to do than mess with anyone who doesn't conform to their idea of what to drive. Probably won't be that hard to fix...maybe get it checked at a repair shop and show the invoice to the facilities guy (like a doctors note!) Try to play along with him like you understand how "important" the issue is, to defuse the situation. Be friendly and don't act like you're afraid of him. "Thanks, I appreciate it, it's all fixed now...." lol.

Oh I used TX-7 additive in my crankcase, it cut down the smoking at startup.
