I have a 1995 ford contour 4-cylinder with 165000 miles on it. I get a code 172 and 519. The car runs fine when going down the road,but surges and stalls at idle.This seems to be worse the more electrical load there is..ie: lights,heater etc. I've changed the oxygen sensor,throttle position sensor,fuel filter,alternater,cleaned out the converter,did a fuel pressure test,checked the egr, plugs, wiring and vacuum lines.I'd really like to keep the car going,its in great shape.Any help you can give me would be appreciated!!!

Code 519 is related to an open circuit or switch on the power steering.
