After driving through some recent snow banks, my 1995 Montero SR suddenly started having problems. Mt oil pressure guage stopped working (cleaned the connectios and now its working). My power door locks sometimes work and sometimes don't. It is hard to even push down the ***** manually and this is on all four doors. Nothing triggers the stop and start of the locks it just happens. Right now they are working but tommorrow they wont. My check engine light is on now, I pulled a code 11 (heated o2 sensor). I pulled out the sensor and cleaned up the connections and put it back in and the light was off for a good 10-15 miles then it came back on. Does the 95 SR only have one o2 sensor? NAPA says it has a pre-cat and post-cat but i did not see a post cat sensor. My ABS light also came on. The snow bank was only a couple feet deep and it caused so much damage. any suggestions would be greatly appriciated.[&:]
