That’s so strange. So far your ST is the only one that has had this problem, that I’ve heard of. I’m wondering if they did something wrong at the dealership. Have you tried resetting the ECU? The car would have to re-learn your driving habits but that might do it. I mean no guarantees but in order to do so you’d disconnect your negative battery terminal and turn your headlights on and leave it for about 10-15mins. Then just reconnect the battery terminal. Then just turn on the car and take it for a little test drive. Now I’m kinda worried about mine. I get my aFe in the mail soon. Guess we’ll have to wait and see.
