I own A Buick Roadmaster 92 5.7 liter v8 I was driving on the freeway and I exited I was about half a block from the exit my car sputtered and died I remove the exhaust manifolds and tried to start it and it started we assembled it and drove home but all the sudden I could only drive it slow and was barely pressing the paddle if I press the pedal to the floor it acted like it wanted to die but if I lightly press the pedal it went so I assumed it was the fuel filter which I replace and it still had the same problem so my next assumption was the fuel pump so I replaced the fuel pump and I'm still having the same problem and I'm not sure what it is I'm thinking it could be something to do with the EVAP system my friend suggested it might be the EVAP purge switch which could be possibly stuck open but I'm not sure your opinion would be very helpful thank you
