Which hose was loose that was causing the problem?

Arghhhh! Back to limp mode. Car ran really well for a day and then pulled code 514 (lo fan speed) easy, hopefully the relay, but also 512 (front O2 sensor) and now code 153 which relates to the rear 02 sensor circuit. I am starting to dislike the myriad of issues that these cars can have . . . starting to miss my 80's Mercedes diesels. I will check plug wires, etc. tomorrow evening but they are bougicard and new as installed by owner. Cap and rotor need to be replaced as it did take some cleanup to get them functional for the test start up . . Oh boy . . . . Oh, and strangely, I tried to pull codes from socket 6, nada, not even a light flash. Any thoughts about this?
