P0380 right ?? with a cold car pull the harness off the plugs and first check that the harness gives out 12v when the key is turned on. you gotta be quick so having 2 people helps a lot. if no juice here the GP relay might be shot.... then use an ohm meter to check the resistance of the plugs. all 4 should be exact same reading. if the computer sees an imbalance between plugs it trips a code. if the plugs are old replace them anyway.
