1976 Pontiac Firebird V8 Two Wheel Drive Automatic 123000 miles
My 1976 TransAm occasionally shifts hard into second gear - there is also an occasional carbuerator popping sound like a mini-backfire. Coud this all be do to an improper timing? I've got 16 degress btdc as a setting but it has not been checked. It has a 400 hp engine and original transmission.
