2003 P71 dies/stalls when making a left turn only.
Any help would be greatly appreciated. I own a 2003 Crown Vic P71 with 43,000 miles. It started last week stalling at a high speed 70-80mph. The Check engine light would flash....followed by the battery light and then the speedo would go to zero (it was down shifting automatically as well). After replacing the ECM Diode problem was gone for a day. It came back in a different form. Now same thing happens when only making a left turn. Someone suggested it may have something to do with the Evap Purge System ?
