O2 codes after head job

[jrm123180]

I just did a complete head job on my D2 because one of the heads was leaking and while they were off I decided to do them right. I was getting O2 codes prior to this (I posted a number of times before while trying to figure this out). Now that I have the motor put back together, I'm getting 0134 0135 0154 0155 I had another set of sensors so I put in the bank 1 & 2 sensor 1 to see if that changed and it didn't. any sugggestions on what these could be or would they possible take a while to go away...I have not driven the car yet, only idled it. Thanks, Steve

Wiring or connector problems - these are codes for continuity problems. See attached pages from Bosch manual on the ECU codes and what voltage values trigger them

Check your front two O2 connectors for green corrosion. Clean them with electric spray and use dielectric grease. Took the dealer over a month to figure that one our on my 2003 2 years ago.
