1993 explorer sport
im driving a 1993 explorer sport 4.0 engine. it currently has 127000 miles and doesnt leak or take a drop of oil.
the problem im having and been having is the smell from the exhaust , it smells like propane . i had it checked on the master computer down at the local ford dealership and they are telling me that all is good and the only prob they see from the computor is its running lean . i allways had a problem with rough idle ,but down the road she does great. i had the cat checked also and its good.
im going to break down and buy two new motorcraft oxygen sensors and see what this does .

anyone ever had or heard of this type of prob.
 






someone correct me if i'm wrong but i thoguth 91-94 only had 1 o2 sensor
 






My 92 only has one:D
 






They changed it in either '93 or '94 (I believe '93)... My '94 has two O2 sensors.
