Wayne Roe: 2007 Mustang GT
Installed the air sensor into a Spectre High Performance air intake. Started engine, initially it revved to 2000 rpm, then calmed down. No check engine light. I began driving, and the engine proceeded to " load up", wanting to stall. I pulled over and shut it down. Restart, same thing. No check engine light. Third try same thing, but now the check engine light is on. Went home, replaced the sensor with the stock unit and all was fine. I called tech service, they said it was a faulty unit.
