First off, thanks to the great folks here for having this.

I have a 2009 Mustang Convertible. 4.0V6 SOHC. Worked great till about start of April 2023. Friend recommended I get it smogged at a place, so drove it all morning, started like a charm, never had an issue. Backed it from my garage and drove 5 blocks to smog place. Turned engine off in parking lot, was told which lane was for smog, started right up, drove it there, turned engine off. They said turn it on and pull it forward on...
