gas dripping fom tailpipe on 2001 Ford Focus

the only thing i have not replaced is the fuel regulater and the main computer system

Asked by for the 2001 Ford Focus
If gas is dripping out of the exhaust it will kill the cat converter. Make sure no injector is shorted electrically and staying open. A scan tool would be nice to see what the on time of the injectors are (see if it is too long). Regulator could be a problem, coolant temperature sensor giving a cold reading could cause excess fuel issues. Do you have a Check Engine Light on? Has anyone looked at fuel trim figures on a scan tool.
