Question about 2001 Ford Windstar
My wind star has an iradic idle I knotis it most when i'm stoped at a stop light my scan tool says that bank 1 and bank 2 are running lean. I think the codes are ?P0701, & P0704? What do I need to do to correct this problem.
The lean condition is caused from the upper intake gaskets and isolation bolts not sealing properly due to time and poor sealing qualities from the factory ther was a service bulliten for this through ford to replace the gaskets,bolts,vaccum line,and lh side valve cover for this concern the oil was getting onto the rubber contaminating it causing a vaccum leak. If you never had the tsb done i would start there, also if there is high milleage on the vehicle i would also clean the maf sensor and resedt kam.

Check for vacuum leaks this is most common cause of both lean codes
