Question about 1995 Volvo 850
My car has been having engine power problem ie loss of power after about 3k RPM. I heard that cleaning the mass air flow sensor and oxygen sensor might fix the problem. I cleaned the mass air flow sensor and cleaned the connectors with electrical cleaner since they were a bit dirty. Then I proceeded to take off the oxygen sensor. As I was taking it off, I was a bit worried about the wires twisting but I shrugged it off and got a cup of alcohol and scrubbed the O2 sensor with a toothbrush. Then I put the sensor back in, and when it was in I noticed that the wires were a bit twisted. Then I tried to start my car, it idled for about a second very roughly then died.
I think that I might have either twisted a wire and broke it or that I loosened up some **** in the sensor and now it reads incorrectly. I really dont feel like spending $160 for a new O2 sensor. Any suggestions?
