Might be a wiring issue? Any evidence of rodents? Exhaust OK? Corrosion at the O2 connectors?

P0134 =
- open or short in the oxygen sensor wiring or connector
- open or short at the oxygen sensor heater circuit
- bad sensor ground
- exhaust leaks
There are reports here of knock sensor wiring being 'disturbed' when starters are replaced...
