Merry Christmas Group Members, While driving my D yesterday I noticed that occasionally when applying the gas the vehicle backfired as if it wasn't getting any fuel. However this was intermittent. At no time did it stall and sometimes when the gas was pressed, normal operation resulted. Could someone point out any weaknesses in the system? Is it the fuel pump or maybe a better question would be where to start looking for problems. Since I am not mechanically inclined could you tell me where to tell my mechanic to start. Thanks and thanks for all of your help this year. Rich
