Gasoline odor/check engine light have had this vehicle machanically checked the smell of fuel on startup with window lowered is overpowering. . The check engine light came on and I had the vehicle plugged into service computer. . Was told too check gas cap/replace. . Which I did. . The gasoline odor is still present and the check engine light is back on. . So new gas cap isnt the problem. There are no leaks anywhere on the engine or at the gas tank, yet the smell of fuel is still present. No gas line leaks. . . We need to make these trucks in America again with american parts. Have always owned Jeeps have a 93 sport in my driveway right now, but this '01 may be my last. . . Literally.
