2003 deville

I INSTALLED THE UPPER AND LOWER CRANKSHAFT POSITION SENSORS, AND A NEW MANIFOLD ABSOLUTE PRESSURE SENSOR ON SATURDAY, HOOKED BATTERY BACK UP AND CAR WAS DOING SAME THING; STALLING IMMEDIATELY AFTER STARTING. CAR STALLED 2-3 TIMES GOING HOME (APPROX 2 MILES), THE WHEN I ARRIVED HOME AND PLACED IN PARK IT STAYED RUNNING. NOW WHEN I START IT I HAVE TO APPLY PRESSURE TO GAS PEDAL TO GET IT TO IDLE HIGH, AFTER A FEW MINUTES OF THIS IT WILL STAY RUNNING.

I AM NOW GETTING A LOW IDLE CODE, AND A CODE SAYING CRANKSHAFT POSITION VALUES NOT LEARNED OR SOMETHING TO THAT EFFECT. IAM HOPING WHITH SOME GOOD DRIVING IT WILL FIX ITSELF.

WHEN CAR IS RUNNING AND IDLING LOW (about 450rpm) the battery light comes on and the service charging system message comes on the "DIC", but if I press on pedal it goes out.

VACATION IN A WEEK, NEED THIS CAR TO SAFELY MAKE IT TO VA AND BACK.

ANYONE OUT THERE HAVE ANY SUGGESTIONS.............http://www.automotiveforums.com/vbulletin/images/icons/icon8.gifhttp://www.automotiveforums.com/vbulletin/images/icons/icon8.gifhttp://www.automotiveforums.com/vbulletin/images/icons/icon8.gif
