What Shop did this? They (SHOULD) have driven the car after the work was done! The DTC will tell the TECH...What the problem is...Could be several Items..Plug wire knocked off..Mass air Sensor NOT plugged in and or defective and a Crankshaft position Sensor. Tell the tech to road test the car then recheck for codes AFTER the test drive!
