2010 FTC XLT Mini cargo w 158k. the Chk engine came on w Mild hesitation. Scanner reported MAP and Low Reference Voltage faults. Replaced MAP and MAF sensors. Wiggled those plus O2 connectors and wiring. Cleared codes and then it ran ok for 25mi. Chk engine came back on w same codes. Plus PCM fault too. Any troubleshooting tips? Thx
