I had a check engine light on and had Auto-Zone check the code. It was bank one knock sensor. I replaced the sensor which is under the lower intake manifold. After I replaced it The car was barely running. I took the manifolds off and rechecked the connection to the knock sensors and they were ok. I found a copule hoses off and when taking off the lower intake that I left a bolt loose on the bank one side drivers side which is where the coolent comes in. I think I might have got coolent in the intake manifold which is causing several code problems now. Any ideas on what to do with these error codes. P0171-P0330-P1133.
