5.0 running rich September 02, 2008, 04:53:57 PM my bird is running really rich and i cant figure out the problem for anything. its so bad that if my dad is behind me in his car he can smell the fumes while its driving down the road. it has been like this since i replaced the map sensor a couple months ago but ive kinda been putting it off but it is getting worse so i gotta get it fixed because its gotta be killing the fuel economy. does anyone have any suggestions where to start looking?

5.0 running rich Reply #5 – September 02, 2008, 07:04:03 PM Well 91 means you have system lean left side. To test to see if it's the o2 sensor swap them from side to side. If the right side throws a lean code replace the sensor. Quote Selected
5.0 running rich Reply #6 – September 02, 2008, 07:11:07 PM okay well i was really planning on getting an x or an h pipe soon, and i already have the headers and gaskets and what not. so i figure if im gonna have to take the time to get the o2 sensors out, i might as well replace it all at once. does anyone have a x or h pipe they want to get rid of near central ohio?

Check under your intake and make sure all the lines are good and not ripped. On my car it actually would cover the ground in black soot. Quote Selected

5.0 running rich Reply #9 – September 02, 2008, 09:01:46 PM the car doesnt throw any visible black smoke, but i do notice that if i let it run in one spot for a little bit there is some black soot on the ground but nothing major. and i do not have a floor shifter, i have a column shifter instead.
