I recently bought a 1995 nissan pickup truck it is a lowrider and plan on fixing it into a really nice ride but i have a problem  the idling is very rough it was running fine then the engine light came on and i put an o2 sensor in changed a fuse and the light is off but now when i come to a stop it wants to quit if I take my foot off of the gas and I was just wondering if you have any suggestions for me.  Please help!!!!!!!!  

ck the I.A.C or Idle Air Control or ajst Idle screw on carb.  

how long has it been since the plugs have been changed? and is it a frontier?
