BING!
the common ibiza lambda malfunction code.
+25% fuel adaoption and next to no volts on b1s1
I suspect wiring/resistor deletes have damaged the ecu
Seen this many times, not found a fix for it.. included rewiring everything to do with lambda direct to ecu, still would'nt fix it.
I think ecu damaged on outputs.. somehow.. Resistors draw too much current out of ecu imhp
i guess the only fix is remove the resistors, check wiring and change the ecu?!
May as well go wideband if changing the ecu anyway no?
