my truck was surging ..finally i got a code 157 ..icheck the output of the maf and reads ok..the ouput of the tps reads negative value when measure from reference to gnd..is suppose to reads positve value..also i have to disconnect the maf in order to prevents and stop the surging at 2000 rpm...this leave me with check engine light on all the time ...when i start to accelerate slowly its hesitates a little but at least is not surging anymore...why is this?help....
