I have a 1996 Pontiac Grand Prix SE 3.1 v6. The car surges at stedy speeds over 54mph I have replaced the catalytic converter and the down stream o2 sensor the service code has gone off the dash but the surging continues. I ve read some of the other question that you have answered and it seems that maybe its the maf but how do i test this? also are any other causes that would not throw a code?
