Why would my Ford 2003 Rnager be misfiring and bucking on the highway at speeds above 45MPH right after I had my alternator, starter and battery changed. Starts and runs great otherwise.
Thanks,

John F.

Check to make sure they didn't reroute any of the plug wires causing one to arc under a heavy load. Also, check to make sure none of the injector plugs were left loose. Finally, check for vacuum leaks. Make sure none of the hoses were disconnected.
