i have a 97 bonneville that i got for basically nothing, thought heads where blown, incorrect, was upper intake around egr melted and puttign water into cylinders, i read a former post abotu the pulsing while driving but fine while on level plane, only proble with your answer is, i changed the egr when i changed the upper intake, granted its not a bad pulse but you can still feel it, i changed the fuel regulator, and twice ive changed the plugs, and wires once, any other ideas as to what may cause it? i was told maybe a speed sensor in teh tranny? but that seems a bit much, any help is appreciated.... thanks!

Hey dcoy,
Pulses as in and out of OD? or does it feel like more of an engine skip? What speed(s) does it occur at? Or all the time? Some more info would be great!!
