Honest Mechanics are hard to find. SST is awesome. I had a Check Engine light come on. They suggested I drive it until near empty, put in a bottle of Techron, fill my 993 with 93 octane, drive it for an hour, unplug the battery, plug it back in. Voila! Check Engine light gone. Who does that?!!! If you have a real issue they will fix it perfect but they know our cars and are honestly the only people you can really trust and take your car to! Others would take advantage of you and tell you that you had an expensive problem when you brought your car in with the check engine light on. They asked questions, listened to the motor and deduced correctly I wasn’t driving my car enough and hard enough!
