We have a chrysler Grand Voyager, it has been losing power on hills to the pint of almost stopping, we had to get AA to bring us home, the EML is on and code P0170 comes up, does anyone know of a common problem with these
Many thanks

 

Bank one fuel trim....

MAP sensor,Vacuum leak, upstream O2 sensor, fuel pump, fuel filter, clogged catalytic converter, or anything electrical concerning those parts... Take your pick. I'm assuming this is a '95 model?

 

Its a 2002 model 3.3l,

 

Most of this applies except you have a MAP sensor and not a MAF sensor. They accomplish the same task just in a different way.
