I have a 1996 Bonneville SSE - and it is doing a weird thing - when I accelerate SLOWLY, esp going uphill, and hit between 49-52mph the car starts bucking and chugging. If I get to 49 quickly, and just zoom past 52 at the same rate - no bucking and chugging -- I have brand new plugs and wires, the fuel pressure is fine, the fuel filter is fine. One board had a similar problem reported on it and they reccommended a catalytic converter change - about a $900 job in my neck of the woods....any other things I can check first ?????? Help! Thanks much.
