Recently had the head gasket go and then replaced. Head pressure tested fine.
About 5-10 miles after picking her up the engine management light came on. Plugged it in and the following came up:
125 - Signal, oxygen sensor before catalytic converter (p0130)
138 - Signal, Knock sensor 2 (p0330)
137 - Signal, Knock Sensor 1 (p0325)
141 - Oxygen - sensor control, control limit (p0170)
These were taken from a print out. Does anyone know what the problem could be to make these codes come up all at once?
