Throttle Body
i have a 2007 chevy Tahoe that recently had a check engine code p0121 throttle body position sensor. The vehicle would rumble when deceleration or braking between 30 and 10 mph. I changed pedal position sensor and throttle body position sensor and still getting that rumble. It less frequent but it is still occurring. Your thoughts??
