steve6 Posted April 25, 2011 Report Share Posted April 25, 2011 just looking for best suggestions on this, fuel pump/pressure ruled out and fuel filter changed.. 1995 deville, 4.9 and no ODB II codes, can you get more detailed info through the dash controls? Starts up and seems fine, once you start driving it, rough idle, chugs until fully warm.. not sure where to start. I don't know these engines, just wondering if anyone who has one has seen similiar issue, or best place to start. Link to comment Share on other sites More sharing options...
