2002 Pathfinder just had motor installed have problems?

Question

It will run perfect until it come to a stop and then it will cut off it will start back up but then sometimes it idles too high or too low....the codes showing are P0506 and P0507 does anyone know what the problem could be?

Answer 1

You might have to go to a dealership and have them reflash the ECU.

Answer 2

you need to clear the DTCs then perform the idle air volume learn with a scan tool and that should take care of the problem.

Answer 3

does it just idle high when your first start up, cause cars do this to get to proper opperating temp. since someone just re did it all i would say its somehthing in the wiring to the computer someone probably forgot to hook something up or hooked it up wrong, i cant think of exactly what it would be and sorry i dont know the codes
