    pinging on hard shifts

    Good idea. I will check the post MAF to intake. In the meantime, I have been to the dealer. Coincidently it was an extremely humid day, right before a storm. Rode with the mechanic and the car did not ping. Couldnt even make it ping. But in talking with him, there was reluctance to do anything...

    Tire Pressure Sensors

    Does anyone know of any aftermarket alternatives to the $60 Ford OEM Tire Pressure Sensor and $60 straps? I am thinking about putting together seperate summer and winter tire/wheel sets for my '07 GT without having to swap the sensors back and forth. Thanks

Do you mean better to run 89 in July-August summer months? The 'ping appears after driving awhile and the car...

    pinging on hard shifts

    I have an '07 GT with 5 speed. 2000 mi on it. I use 87 octane. The car has begun to ping when shifting into second or into third, on hard shifts. Not on easy shifts, not in higher gears, and not when just stepping on it to pass. Only on hard shifts in the lower gears. Has anybody experienced...
